The Spain international, who started his career at the Nou Camp, is struggling to recover from severe bruising to his knee and leg suffered during the Barclays Premier League clash at Birmingham.
The Frenchman confirmed: "He did not train and at moment he is not fit to play. We will give him 24 hours more, but I don't know if he will be available.
"If the game were on Tuesday, he would not play. If he is not capable to play, I would not take a gamble and put him on the bench."
