Now Real Madrid must fight to win the remaining several matches in the UCL in order to qualify for the next round, Ancelotti will definitely take advantage of the players sitting on the bench to replace injured players. Ancelotti has to work hard to keep points so that he is not far from Barcelona in the La Liga standings this season.
There are news that Real Madrid are going to sign atleast 4 players and 2 players deals is already sign, I'm not sure how reliable this rumors are but they are trying to make some good moves to patch the injured players. I think that Anceloti confidence in his squad has reduced, people were more interested in players he was going to sign but he seems not to be interested in many and now he needs them now that the league is serious.
There is this pattern I have notice from clubs that win the Champions Leagues irrespective of any other trophy they won, any team that won the Champions League, they do later suffer from a lot of injured players and that's what is happening to Real Madrid. Defender is weak and the goal keeper is not serious anymore, they need Courtois to come back or get someone better than Lunin otherwise they will not go far in this season that Barcelona didn't come to play.
