I'm not worried. Ancelotti as an experienced coach certainly knows what to do to maintain the solidity of his team when injury problems come. Although it cannot be denied that it will affect their performance on the field. Real Madrid is still a big team filled with talented players, both core and reserve players, moreover Madrid always has a way to get out of pressure. Yes, in the next match before playing El Classico they must first face Dortmund in the UCL, two tough matches are waiting ahead. Ancelotti must really maintain the fitness of the players because they only have 4 days of rest from UCL to El Classico.
