Didier Drogba is set to complete another U-turn over his long-term future at Chelsea by agreeing to sign a new contract extension, according to adviser Thierno Seydi. Drogba's current deal, reported to be worth £90,000 a week, expires in 2010.

The striker, who has remained unsettled at Stamford Bridge since 2006, and seemed certain to leave after falling out of favour under the former manager Luiz Felipe Scolari, has been repeatedly linked with a move away from England this summer. But Seydi says the Ivory Coast forward would now be willing to stay after rediscovering his form under Guus Hiddink's management.

Seydi said: "Didi has a deal with Chelsea so he is relaxed about his future. He is happy, playing well and his return to form and scoring goals points to the fact he is enjoying his football. In football you can never write anything off. There are big opportunities at Chelsea, so we will see what happens. If they present a new proposition then we will consider it and after that Didi will make a decision on his future.

"It was important for him to return to his best level, without bad injuries, and he has shown he's one of the best players in Europe. A lot of big clubs in Europe have asked about him but we will not make any decision until the end of the season."
