It's not that Real Madrid is doing very well in the League, they have let Barcelona take a lot of advantage, I don't know if they allowed themselves to take that advantage out of confidence or because Ancelotti's strategy was not correct because they didn't give the results, In the same way they have a very hard job, I doubt very much that they can catch up with Barcelona, this time like the League got out of hand, the only hope they have is to win the UCL. and they can do it, they have the material, also if Ancelotti wins the UCL I think he would be saving his position at Real Madrid.
Does he have anything to save? I mean, there's nothing to kick him off the team for. Maybe he didn't take first place in the league or win the Champions League, but not everything depends on him, a lot depends on the players too. That is, as a coach, he does his job very well and I see no reason to change the coach. Another thing if they were in the 5th place in the league for example
Barcelona is relatively ahead of Real Madrid in La Liga. Because Barcelona has been unbeaten in the last few matches but Real Madrid has drawn some matches. However, Real Madrid still have many opportunities to improve.
