Here, we take a look at some of the contests key battles.
SAMUEL ETO'O v BENEDIKT HOWEDES
Cameroon forward Eto'o, a Champions League winner with Barcelona and Mourinho's Inter Milan, is slowly finding form after a less than prolific start and scored his first Chelsea goal against Cardiff. Schalke skipper Howedes will be assigned the task of shackling Eto'o, poised to lead the line in the absence of Fernando Torres.
