Alex Song v Cesc Fabregas

The duo know each other well having spent time playing for both Arsenal and Barcelona together – but will be rivals come kick off.

Given Chelsea are missing key man Nemanja Matic and injured John Obi Mikel, the role of Cesc becomes more important to Chelsea’s hopes of success and Alex Song will probably be tasked with trying to keep the Spaniard quiet.

Depending on how Jose Mourinho sets up, Cesc could be deployed further up the field or at the base of the midfield two next to Ramires. Either way, if West Ham want anything out of the game, they will have to win the battle in the middle and Song is key to that.
