I think that would be nonsense. Real Madrid doesn't need an attacker. Real Madrid needs a defender. They have one of the best offensive lines in the world right now. Maybe Ancelotti should decide how to use Mbappé. Real Madrid has lost a lot of points because of his poor form. He plays very selfishly and that's why the other players in Real Madrid are also uneasy. Maybe if they don't play him for a few games, the team can improve. So it doesn't make sense to buy Mohamed Salah or another player.
Only conceding 13 goals from the 15 matches they played, I think that is still within reasonable limits, but they felt it when they were having a hard time scoring goals so that's what caused problems for them. I myself agree that all positions in Real Madrid need to be refreshed, because I see what they are experiencing right now as the result of the team's performance not being too optimal.
That is indeed caused by several factors, one of which is because many of their players are injured. But apart from that, the performance of several players is also not optimal, I don't want to point to individuals, because again that is what ultimately causes problems in their performance.
