Yes Real Madrid didn't play well yesterday Vs Real Sociedad in their Copa Del Rey semi final game. Some players were missing form the squad, I don't know if it's because of injury or they were kept purposely by the coach for Saturday and Tuesday Champions League game Vs Atletico Madrid. Just this morning I read that Ceballos was injured and will be out for up to 2 months, another blow and bad news for Real Madrid considering their fixtures right now.
Why Real Madrid didn't play well? The won the match, right? I think there was no problem with Real Madrid performance. Yes, there were some main players missing from the lineup because of many reasons. Mbappe has a problem with his tooth, meanwhile other players may need time to take a rest. If Ancelotti rotated some players, I think it was good because Real Madrid has many important players in the near future. As long as Real Madrid won the match, I think Real Madrid already did their best. They can beat Real Sociedad with bigger scores in the next Leg.
Ancelotti rotated some of his players, we realize that it is necessary to give rest time to star players. In addition, this decision can provide playing opportunities for a number of second-string players. Therefore, I think it is reasonable if they are only able to achieve a narrow victory at Real Sociedad home. I am also sure that in the second leg, Real Madrid will be able to score many goals. Ancelotti certainly has enough experience in understanding the intensity of competition in each competition, and currently his priority scale is La Liga and the Champions League.
