Hazard: Chelsea were frightened of Man City

The Belgium midfielder says the Blues ultimately paid the price for a slow start in their FA Cup semi-final, having shown too much respect for their opponentsRafa Benitez's side found themselves two goals down minutes into the second half and were unable to produce a comeback despite Demba Ba pulling one back late on. The Belgium international says the Blues were "frightened" of Roberto Mancini's men in the opening period and that ultimately cost them a place in the final against Wigan. "We were frightened of City in the first half," he told The Sun. "We showed them too much respect, and paid the price. Maybe we might have deserved a different fate, but we started the game badly. "We played the final 40 minutes, but that is not enough to beat City. "We had chances, and we believed we could do something, but their keeper made some good saves." Chelsea face Fulham in the Premier League on Wednesday hoping to claw themselves back into pole position in the race for the Champions League. Rafa Benitez revealed that Ashley Cole will miss the game but is getting closer to a first-team return. "He will not be back for Wednesday. He is getting closer but not for this game," the Spaniard ..

MAKING HUG SOME OF MONEY WITH BLACKBERRY

How To Make Money Online With Your Blackberry This is a guest post compiled by Olokede Olawale Over 60% of smartphones users in this part of the world make use of Blackberry and the device has moved from what the rich can only buy to a device for all and sundry. A research carried out in Nigeria revealed that most people use blackberry for fun than for business purposes. For me, my blackberry is not just a device that I use to update my website- www.informationnaija.com on the go but I also make legitimate cash on it. I will explain how to make money on blackberry and am sure this will be useful to bloggers,publicists and webmasters. STEP 1 - Requirement You must have a lot of contacts on your BBM (Blackberry Messenger). Currently, I have 1200 contacts on my bbm and I know of some people that have 2000 even 5000 contacts. In my next post, I will be sharing with you how to get a lot of bbm contacts in a week. STEP 2- Money Making Messenger For you to make money, it involves just a thing or an act which is by broadcasting someone's paid adverts to all your contacts. STEP 3- How To Get Adverts To Boradcast on BBM Getting adverts to broadcast is so simple, I will give you some hints. ==> You can broadcast this: "Promote your products, events, business to over 2000 BBM users in Nigeria". After that am sure some people will be interested to do business with you and bill them. I currently bill my clients N500 per broadcast. ==> Change your display name to a name that can be easily search for on BBM. If your name on bbm is full of smiley faces,signs and symbols or some funny letters then it will be difficult for people to search for you. So, it's better you change your display name to your website name or your real name without any 'swag' sign. ==> You can also get advert by replying any broadcast that includes someone's products or services. NOTE- Do not lie about your contacts to your clients because some of them might request you screengrab your contacts list. I hope this makes some sense. If you have other ideas on how to earn money online with Blackberry, kindly relay them via comments.getrich or die tryin

My Attractive B00bs are my selling point – Chiege Alisigwe

Chiege whose angelic face has been scarce on movie jackets lately, reveals the reason she has been away for so long, what she has been up to and also her very unique selling point, in this up, close and personal chat. Enjoy, You recently set up an NGO. What is it all about? What I had in mind when I set up my NGO was to use the platform to reach out to the less privileged people in our society. You know, somebody might be looking good but inwardly, he or she has a lot of problems bothering him. So, we really want to see how we can assist them in our own little way. Have you reconciled with your husband? I don’t know. I hate talking about my private life. But what I know is that I have a child now. Which part of your body do you like most? There are certain things God blessed with that make me to feel like a real woman. They are my Melons and my face. I am not saying that anybody who is flat chested is bad, the person still looks good. But if I dress, i will first admire myself before the mirror, I always thank God for making me a complete woman. Like something you know many are paying to have, I have it naturally. And I thank God the way he made me. I am very grateful, I cannot ask for more. Like how much can you insure these places you like most? Money cannot be enough when it comes to those areas. I don’t pray for anything to happen to these places. I am ok the way I am. Are you comfortable with the kind of movies that are coming out of Nollywood? I am not comfortable at all. Though there are some good movies, the fact remains that Nollywood needs to step up its game in the area of production. Because, majority still need amendments here and there. I want the industry to produce quality movies . I want them to come out with something more challenging. How has married life been with you? Well, married life is good. Though there are ups and down, it is sweet at the same time, it is sour. You cannot just say it is all bed of roses but it is good. It is good because when the going is sweet, you love it the more but when the going is bad, you will still be there provided it is not life and death. Does your marriage affect your career (Acting)? No, it does not. You stopped acting for a while now, what happened? No, actually, I didn’t stop. But somehow, you do not need to act one million movies in a day. You have to advise yourself, I am the married woman that wants to combine my family with my career, and then you have to compromise. You think about your family first. No matter what you do, your family comes first. How did you start acting? Well, that was in 1998. When I left secondary school, I took JAMB; and I entered into the movie industry. To me then, it was a sort of whiling away time while I was still waiting for my JAMD result. Not like now you see people desperately want to act. It was not like that for me. Was it like a passion you wanted to use to pass time? Number one, I love acting because, I use to act drama in secondary school then. Secondly, I was waiting for my JAMB result so I want to use that to while away time. Because, I don’t like staying idle. Even as a child, I used to do one or two things. I have always been an independent person. I would say that I started acting because I hate idleness. How many movies have you acted this year? I don’t really know but it is not much. You live outside the country most often? I live here in Nigeria but most times, I travel out of the country because of the project I’m embarking on. I shuttle between Nigeria and the outside world. There are certain things I need to bring from there to this country that is why I travel most often. Like my cameras, I brought them down from there. Like the house of service I told you, I need some in Nigeria and likewise outside the country. Like other actors and actresses who have ventured into the music industry. Are you planning to do the same? I love singing, I have sang so many songs. But, we cannot keep acting all the time. Because if you continue like that, you can never have your time, you can never give your family that time they need. You act, you get another thing to fall back on incase if you are not there. At the same time, you cut your shot. What I mean is this, if you are the boss of what you are doing, you can say, let me give this time to my family today and your assistance will take over. Also, tomorrow you can say let me go to work/location today. I don’t want to spend all my time in working (acting). Where I can be answerable to somebody without being answerable to my husband. So, you have to initiate something on your own by so doing, you can tell your workers, go and do this thing and you will go and relax. You can also be doing other things that will give you time to attend to your family. That does not mean I would not act for anybody anymore. I will act for people but I can never be the same like when I started as a young girl who does not have anybody to answer to. Does it mean you choose the roles you act now? Yes. I choose. I see the script. If I am not satisfied with it, I will tell you that I cannot act the script. If I am satisfied with that, I will go on with the script. Do you think you still have a chance in the industry considering the number of actresses who are eager to act? Well, I don’t look at people’s faces. I believe that whatever you are, it is on your own. If you are good, it is for your own good. I always tell people to be confident in themselves. If you have self-confidence and a dragon is by your side, you can even say hi to the dragon and go your way the dragon would even turn back to follow your footsteps. Just be contended with yourself, how you act,, do you thing in your own way. Don’t mind how people do theirs. You will find out that a lot of people are out there who are following your footsteps without your knowledge. So I am not scared. What are the challenges you are facing now? Talking about my challenges now, I think it is what I am building up that is giving me lots of challenges. The other challenge an actor/actress can face is that professionalism in the field, knowing what you are doing. By God’s grace, we have the professionals in the industry. In fairness, I even love challenges so much. What is your driving force in creating your own studio? I decided to create my own studio because, I wanted something different apart from my acting. It is a kind of gradual step you have to take when you want to be there. I do not really want to have problem when I am there I will start looking for cameras or anything. I want to gather everything before I start the NGO. So that when I am out, they can finish everything without problems. What do you intend to do with your NGO? Ok, we want to reach to people because, so many Nigerians are hungry and I think I am happier if I am eating and the person beside me is eating as well. If am eating and the person beside me is hungry, I feel so unhappy. I derive joy in making people happy. When do we hope to hear about the NGO well? Not now because we are still working on it. Tell us about your background? I am Chiege Alisigwe from Orlu Local Government Area of Imo State. I am the last in the family of Eleven. I read fine and applied arts. I did my OND at Federal Polytechnic, Oko, before proceeding to IMT Enugu for Higher National Diploma. I did my youth service and now on the verge of doing my masters.

Nollywood movie stars engage in s*x game on movie locationNollywood entertainers’ engagement in adult game on movie set is not a new thing and to further verify the story, Nigerian Yoruba actress Mojisola Olaiya popularly called Moji Olaiya has come open. In a recent interview with Kayode Aponmade, see Moji Olaiya’s response below; Kayode Aponmade asked: But do you agree that actors and actresses sleep with each other on location? Moji Olaiya said: It is possible. s*x is an adult game that requires both parties to agree. Since no one has ever complained of being defiled, there should be no complaint about that.

28 Year old Vegetable Seller Gang Raped In Lagos [Pics]

Evelyn was a vegetable seller...On one of her numerous trips in search of her livelihood, she was manhandled and molested by five hoodlums in the presence of her friends. How did it happen? National Mirror explains below: A five-man gang of robbers forcefully had canal knowledge of a vegetable seller simply identified as Evelyn. She was allegedly sexually assaulted in the presence of her two colleagues. Evelyn, a resident of Ojo area of Lagos State was at the back of a church along railways line, in Oyingbo area. It is the practice of those in that trade to pass the night at an open space in the area, while waiting for the trucks that convey the commodity from other states in the country. The purpose was to get the freshest of vegetables to sell the following day. Evelyn, 28, who had reportedly been in the trade in the last five years, usually joins her colleague in the vigil waiting for the trucks. In the early hours of Tuesday, April 2, 2013, Evelyn, as usual was among the horde of traders waiting for the truck bringing vegetable into the market. That day, the truck delayed a bit. Around 12:30a.m, Evelyn told two of her colleagues that she wanted to have a stroll down the sparsely busied street, hoping to have something to eat. The two friends reportedly joined her. The three traders trekked some five minutes down the railway line and they came to the kiosk where fried breads and eggs are sold. The kiosk was owned and manned by a Hausa trader. The three women therefore settled down at the grocer’s kiosk and ordered for food to be taken back to their temporary abode. While the grocer was busy frying the eggs, the suspected robbers/rapists stormed the kiosk, launched an attack on the man. The bread seller was reportedly beaten to a stupor by two of the robbers while the three of them swooped on the three women. While two of the women managed to wriggle out from the claws of the suspected robbers, Evelyn was not as lucky for she was reportedly haggling with the grocer over the price of meal in the innermost part of the shop when the hoodlums struck. It was reported that the five men dragged Evelyn out of the shop and whisked her to a corner close by and where they took turn to rape her while the bread seller wriggled in pain on the floor of his kiosk. In the end, the grocer was reportedly robbed of a lot of cash and mobile telephone sets. The two women also lost their GSM handsets while Evelyn also reportedly lost some money to the robbers. But rescue came the way of the molested woman when her two friends who raced out of the place ran to Denton Police Station to lodge a complaint of what had just happened. The noise of the two women and Evelyn herself probably drew the attention of men of the vigilance group patrolling the area to the scene of the rape. The vigilance group reportedly swooped on the robbers cum rapists and engaged them in a fight. Four members of the gang were later identified to be Saidi, Jamiu, Kashimawo and Atoba. In the end, Evelyn was rescued while three of the rapists were apprehended and handed over to the police at Iponri Police Division. Evelyn managed to narrate her ordeal in the hands of the rapists thus: I have never experienced this in my life. Two of my colleagues and I, while waiting for the truck to bring the vegetable were hungry and decided to take a walk down the railway line, knowing it is always a beehive of activities at that time of the day. While we were there waiting for the Mallam to fry the egg, we just saw these men walked in and we thought they also wanted to buy something. The next thing we saw was that they started beating the Mallam while some of them dashed towards me and grabbed me. My other colleagues were lucky to flee the scene but because I was negotiating with the Mallam right inside the kiosk, I was not so lucky. That was how the men dragged me with them and carried me to one corner and molested me. Speaking on the development, Agbodemu Ishola Musbau, a community leader and head of the vigilance group that apprehended the rapists, claimed that the rapists/robbers were members of the notorious gang that has been terrorising the community in the past couple of weeks. National Mirror could not get the comment of the Denton Police Station as its Divisional Police Officer was said to be away while none of his subordinates was ready to speak with the press.
