Essien certainly would be an improvement on Mikel, but I wouldn't fear a midfield four of Deco, Lampard, Ballack and Cole - they could hurt us in the final third of the pitch but they wouldn't have the workrate required when they didn't have the ball. Drogba can be phenomenal when things are going his way but we also know from experience that he may as well not be on the pitch when things aren't going his way - Agger and Carragher have shown themselves capable of nullifying him in the past. The mentality of Chelsea has changed since Scolari took over, they have lost the combative edge that Mourinho gave them and Grant maintained.
