Marseille are currently suffering major striker problems, with all 4 first team strikers carrying injuries. As there is no clause in the loan contract for Marseille to recall Cisse, it was completely down to the player, in which he was opted to stay with Sunderland.
Gerets had this to say, "I didn't throw a party when Cisse left, I predicted this situation when he left. I said: 'I hope nothing happens to Mamadou'."
"Unfortunately, it did, and we've had a few problems ever since."
