Ancelotti is trying to increase the experience of the young players in his squad. In this match, Ancelotti has kept Rodrygo, Arda Guller and Endrick in the squad. Although Rodrygo gets a regular place in Madrid's starting XI, Arda Guller and Endrick do not get a chance in Madrid's starting XI. Along with the young players, Ancelotti has kept experienced players like Modrich in the squad in this match.
Madrid did not play very well, but Real Madrid won the match. If Madrid's defense was strong, I would have said Madrid played well. Real Madrid won 3-2 in a misunderstanding. However, it is proven that Madrid has been able to find some talented young players. They will be able to strengthen Madrid's squad in the future.
Because this competition is not a priority for Real Madrid and because the opponents they face are of a not very strong level, Ancelotti has made a step which is actually quite good if the aim is to provide experience for young players or second tier players who rarely get playing time in other big competitions such as the UCL. So in the Copa del Rey Ancelotti can give opportunities to players who rarely get playing time. And yes, the quality of the attack line is still quite good. The only weakness is in the back line.
What really makes me curious is the next match that Real Madrid will face in Laliga, namely against Atletico Madrid. I'm curious whether Real Madrid's current condition can still be superior to Atletico Madrid or not. I hope Real Madrid wins. but I dare not favorite it. because Atletico Madrid is also in pretty good form at the moment.
