Mikel Obi signs new 5-year deal with Chelsea

John Obi Mikel has signed a new five-year deal with Chelsea, tying the Nigeria defensive midfielder to the European champions until 2017.

Mikel, who joined Chelsea from Norwegian club Lyn Oslo in 2006, says on Wednesday "I have basically won everything with Chelsea and those (six) years have been really special for me."

The 25-year-old Mikel has won one English Premier League title, four FA Cups, a League Cup as well as the Champions League last season.

He has been a regular in the side since the departure in March of manager Andre Villas-Boas, under whom Mikel lost his regular spot in the first team.

Mikel says "I think I am now hitting my peak but as a player you want to improve every day and there is still room for that."
