Just an opinion but why don't we actually change our formation and play Torres, Drogba, Sturridge and Mata in the SAME lineup.
Cech
Ivanovic Cahill Terry Cole
Ramires Essien
Mata
Sturridge Drogba Torres
Maybe change that formation into a 4-2-2-2 instead of a 4-3-3 which clearly hasn't been working.
