Chances are Flappy has to stay. Seems his injury could keep him out for a couple of months. Difficult for him to get that move if he is injured.
Improved contracts for a few players and the purchases + wages of Gervinho, Oxpot, Arteta, Mertesacker, Jenkinson and Santos - there is the Cesc and Nasri money.
Dules, the money you are talking about, (Ade, Kolo), has already been spent on paying off our debt.
