Moussa Dembele will not play as he continues to struggle with his hip problem that has kept him out of the club's last eight games. The Belgian had hoped to return for the crunch match at the Emirates Stadium, but Villas-Boas confirmed on Thursday that he would not be ready.
Sandro will have a late check on his calf injury but Scott Parker (Achilles), Benoit Assou-Ekotto and Younes Kaboul (both knee) are not expected to feature.
