Chelsea's John Obi Mikel has answered questions from fans via Twitter about his five - and - a - half - year goal drought for the European champions. <br /><br />Mikel's last goal for Chelsea was early 2007, and he is not bothered he is often criticized by the supporters for his lack of goals.<br /><br />'' I'm not always in a position to score, so I don't score, that's the truth. I've always had to sit back and keep the shape.<br /><br />''When I go forward nobody will cover for me so the midfield is open. I hope people see this because I don't know when that goal is going to come! I think I would have to change my position slightly to score goals,'' said the defensive midfielder.<br /><br />Super Eagles colleague Victor Moses completed his switch from Wigan to Chelsea in August after months of speculations surrounding his future. Mikel believes the youngster will be a hit at Stamford Bridge.<br /><br />''Victor Moses is a good guy. He has come in and he's a bit shy but as time goes on he will settle in. He's a fantastic player, a good addition to the team and when he settles he can show off what he can do. He's very skilful,'' he added.<br />
