Chelsea have opened talks with striker Didier Drogba over a new contract at Stamford Bridge.

The Ivorian, whose current deal expires at the end of the season, has reportedly been offered a one-year extension.

"His level of performance has been outstanding, helping the club and teammates," said manager Andre Villas-Boas.

"Of course, the club have to agree that players who perform are the players who should continue.

"It's an ongoing talk with him and his people."

The Blues host leaders Manchester City in the Premier League on Monday night.
