Ivory Coast striker Didier Drogba will leave Chelsea when his contract expires at the end of June, the Premier League club said in a statement yesterday.

Drogba, 34, joined Chelsea from Olympique Marseille in 2004 and scored 157 goals in 341 appearances for the club.

"I wanted to put an end to all the speculation and confirm that I am leaving Chelsea," Drogba said on the club website.

"It has been a very difficult decision for me to make and I am very proud of what we have achieved but the time is right for a new challenge for me."

Drogba has been linked with a move to Shanghai Shenhua where he could join up with former Chelsea teammate Nicolas Anelka who left Stamford Bridge in January.

Drogba enjoyed a glittering eight years in the Premier League in which he won three league titles, four FA Cups and two League Cups. He capped his trophy-laden career at the West London club by starring in its Champions League final victory over Bayern Munich on Saturday, when he scored a late equalizer before netting the decisive penalty in the shootout.

"Didier is undoubtedly a Chelsea legend and will always be part of the Chelsea family," Chelsea chief executive Ron Gourlay said. "He is certainly leaving on a high after Saturday night but he feels the time is right for a new challenge.

"We have known for some time that this outcome was likely but Didier and the club only made a final decision on that in the last couple of days, because for obvious reasons neither Didier nor the club wanted to distract focus away from the Champions League Final.

"The talks were amicable all the way through and we wish him all the best for the future. He is welcome back to Stamford Bridge at any time - either as a player or as a guest of ours."
