Madrid will not like to lose against Barcelona this weekend because they don't want the point to be closer because the season is not finished and anything can happen, and they won't try to make any mistakes thematic that can cause them to lose or draw against Barcelona this weekend. I believe with Ancelotti he won't mess up in the game, but I notice some of Real Madrid's players are tired since the match against Manchester City, and I think Ancelotti will beach some of his key players. But Ancelotti needs to put some squad to prevent losses because as I see Barcelona, they are unhappy since PSG eliminated them in the Champions League they will like to revenge against madrid this weekend, but he won't be and easy task for them.
With the kind of spirit that Real Madrid is currently harboring I dont think any club out there can easily defeat them including Barcelona right now because the last win against Manchester City have gracefully strengthen them to be more fierce and their level of delivery.
All Real Madrid needs to do now is to put in same energy or something little more than they had in the last match and I can guarantee that they will win this El Classico. I dont think Barcelona will be as strong in terms of performance like Manchester City did in the last match at the Champions league quarterfinals
