Most likely Real Madrid can win the game against Chelsea, but I doubt Real Madrid can win the game against Bayern or Man City in the next round.
After Real Madrid's performance against Barcelona yesterday, I saw some supporters of Chelsea who insisted that if that was the current form that Real Madrid is, where they were struggling to score goals, that they were going to win them. The game Real Madrid played was in the Spanish league, and the not the champions league. Real Madrid play differently in the champions league regardless of their form in the La Liga, Chelsea do not need to think that Real Madrid will be an equal challenge to them. Both teams are not having a good time in their domestic league.
IMO, I'm guessing. In last night's match, Don Carlo was trying to experiment with his formation, he implemented the 4-2-3-1 pattern. unfortunately, the result is not effective. and that doesn't mean Real Madrid was unable to keep up with Barcelona's game in the El Clasico match. in the second half, Ancelotti returned to his usual formation with a 4-3-3 pattern, and the situation changed quite a bit. Madrid was able to offset the game from Barcelona, they even had several opportunities. Unfortunately, Asensio's goal had to be disallowed by VAR. even though Madrid lost, at least the games of the two Spanish giants were quite even.
Referring to the quarter-final match later. on paper, Madrid has a higher chance than its opponent. moreover, the first leg match will be played at the Santiago Bernabeu. so, however Madrid is more in the favorites to qualify for the next phase. after all, they have advantages over other teams. that is, the mentality of a champion.
Speaking of Chelsea, I don't want to take Graham Potter's team lightly. however, their performance has not shown significant changes. plus, the system that Potter implemented didn't seem to work the way he wanted. I don't know, maybe something is an obstacle in their locker room. however, because this match still has a time lag. at least, the two coaches will maximize their team to perform optimally in the match later. so, let's wait.
