The performance from osassuna was actually very different compared to when madrid faces manchester city. Madrid looks incompetence int he match against osassuna compared with city but i do know that if real madrid didn't wanna try to put its players under pressures against osassuna.
I don't see that as a serious problem right now caused by osassuna was losing against madrid. It has not become an important question anymore. Real madrid needs to focus against manchester city rather than la liga right now.
The gap between madrid to the competitor below it is still very far. It will not be a big probelm for real madrid to lose another three points as long as madrid will able to win against manchester city.
Indeed, in the first leg match against Manchester City, Real Madrid appeared quite impressive where they seemed to have managed to do their best compared to their previous game in the laliga. Therefore, some facts are true where Real Madrid saves special energy only for the Champions League. A draw closed the first leg of the semi-final between Real Madrid vs Manchester City. This result makes the chances of both still pocketing 50|50 in the second leg later.
Of course Real madrid don't think about the importance of laliga matches for the remaining few matches in this season, because they only need 1 more win that they can try to close the season in the top 4. But the draw in the first leg against Manchester City is quite disappointing for me because I was expecting they could have won the match but the goal from kevin de bruyne made my hopes dash.
I would like to emphasize that I have so far never seen a team that was able to take Haaland out of the game like Real Madrid did against Manchester City. He was almost non-present on the pitch. Except for his header and his one left foot shot, he played no role in the game. It almost hurt to see him being so passive, but it is not only his fault. There wasn't a single precise pass in the free space or a cross ball that came close to him. He was eliminated from the game by Alaba and Rudiger and as I said, I've never seen a defense doing it like Real Madrid pulled it off.
