“Both sides have injury issues. Jose Mourinho has continued to maintain that Diego Costa will miss out with his mysterious hamstrings/groins and a bug, while Loic Remy is a major doubt after limping out of Tuesday’s 6-0 Champions League win over Maribor clutching his groin. That could mean Didier Drogba starting as the one forward – a concern, given how off the pace he looked against Schalke 04 in the Champions League, the only other game he has started this season – or Chelsea could perhaps go with a false nine. They did that last season in the stultifying 0-0 at Old Trafford last season, but Andre Schurrle, who occupied the role then, is a doubt with illness. Chelsea are also without Ramires and Mikel John Obi.” Bet – Jonathan Wilson
