John Obi Mikel says he is fit for Chelsea's huge home game against Manchester United this weekend.

The Nigerian midfielder missed the Premier League leaders' last three games with an ankle injury.

But Mikel now insists he is ready to rejoin Carlo Ancelotti's squad for the crunch showdown with second-placed United at Stamford Bridge.

He has also been called up by Nigeria for their must-win World Cup qualifier against Kenya in Nairobi on Saturday week.

Mikel said: "I will hopefully start playing again this weekend. I'm also looking forward to helping Nigeria.

"It is very important for us to win. We all have to work hard and simply pray that the result favours us."
