Well you can't blame him, of what use is signing players when you don't give them chance to play. Anceloti has favourite and I don't know why he does that most often he has his best start players but unfortunately half of them are in injuries and he doesn't have choice than to use the reserve players but even at that, he doesn't seems to satisfied with the bench players, he prefer his best starter despite the reoccurring injuries they get all the time.
Don't be surprised that by January time, he will not sign any player. He is very stubborn, I don't know why but perhaps he has his reasons or because Real Madrid been one best club in the world, they don't like to dilute their teams with players that much so that the credibility of the team will remain intact but then, the team can't continue like this unless the remaining players are able to put the team performance in a maximum place.
