Is it because there was too much gap between them and Barcelona? Madrid wanted the league title from the beginning of the season. They were focused on all competitions. Before the world cup break Barcelona were topping the league with just one point difference Madrid was at second position.
How do you say they were only focused on the champions league but they won the copa del rey.
Real Madrid is a big club and they want to win La Liga as well as Champions League. They did not focus on Champions League only and sacrificed La Liga at the season start or before World Cup ending. I don't know what actually happened in Real Madrid after World Cup 2022 but their performance in La Liga dropped a lot since January, after World Cup ending. Perhaps their players were tired and lacked of focus on La Liga. They lost many points because they could not score winning goals.
Gradually they fell more behind Barcelona till a time they had to decide to only focus on Champions League but it is not their initial plan.
Real Madrid were just inconsistent in the league because that is the kind of coach Ancelotti is. He has never won a single league title twice with the same team in his career, and I'm certain he will not win the La Liga again with Madrid.
I don't think so. We must think back that two seasons ago, maybe many of us did not think Real Madrid could win Champions League with many old players. They and Carlo Ancelotti won that Champions League and in the past season, they were not too far from another Champions League final match. With old players, it is more difficult for them to maintain good performances in a very long league season and perhaps it is their biggest problems in the past season.
