I think Rafa was just sticking to his players to see if they can make the lone striker system work, it obviously didn't, other managers might've stuck it out longer than he did. Takes a big man to change your ideas early on in the season I personally think he'll get rid of Cisse and bring in another striker and continue playing the 4-4-2 as the starting formation for 90% of the games, perhaps without Moro and Crouch partnering (Even though those two are doing very well together atm), just to strike a better balance upfront I don't think he'll change much even if he brought new players, if it ain't broke don't fix it and all that. He'll just buy them to expand his possibilities Under Rafa, we can play under numerous different shapes anyway, so we really don't have any set formations, 4-4-2 atm is probably Plan A, but the man has B, C, D, E, and so forth, he's that good
