Chelsea hero Ray Wilkins believes the club will struggle to fill the void left by Didier Drogba.

Drogba, 34, quit the club to end his career in China with Shanghai Shenhua.

And Blues legend Wilkins believes Chelsea will change the way they play, starting against Manchester City at Villa Park today. He told The Sun: "They have lost the world's best out-and-out centre-forward over the last eight years in Drogba.

"It looks like they might play quicker through the middle but they'll be trying to bed-in new players which will be difficult."
