Drogba is in sizzling form with 12 goals in 13 games.

The Sun quoted Deco, 32, as saying: "The big difference between us and United is in attack. Drogba is enjoying a spectacular moment in his career and is superior to the front-line of United."

"For me, Didi will be the key - the star of the match, for sure," he added.

Leaders Chelsea are two points ahead of the Red Devils.

"This match has a four-point value, an extra one for the blow to United's morale because they also failed to beat Liverpool. If they fail in London they will need to think very much about things in the following days," Deco said.
