Ancelotti should have done it in the summer transfer window, but he said he would not recruit any more players. As the league started and at the same time the national team's international match schedule, Madrid experienced many players who were injured. Talking about defenders that Madrid had targeted or were linked, Magalhaes and TAA, were rumored to be recruited by El Real. But I'm not really sure if Arsenal will release this Brazilian defender, unless Madrid offers an attractive price for Arsenal. But it seems that if Madrid will recruit several players, especially defenders, there are actually still many options and they are also good. In fact, sometimes Madrid brings in players who were not expected before. Let's just wait for the next rumor, whether Madrid will indeed target new arrivals in January, or they will evaluate it at the end of the season.
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.
