I mean the joke about how Vini and Mbappe and Rodrygo were all at left wing for a while is true, for a short while that happened, normally that is not the case but they all switch places at all times, they do not have a set position to play, I have seen Mbappe at left and Vini at striker many times too, and even Mbappe a bit back and Jude ahead. He just does whatever he wants with the tactics and players, and because it gets results nobody questions him, looks horrible but then gets a result of they are looking to keep doing what he is doing and will forever be happy as long as they get the results.
I totally agree with you. This was one of the reasons why Real Madrid's overall performance was not stable. Players failed to select their position correctly. Talented players like Mbappe, Vini and Bellingham cannot play in their own positions. So Ancelotti's match strategy works properly in this match.
Real Madrid players have not failed to select their positions. They were only trying oversaturation on one side. That's why you saw that it seemed all of Real Madrid's forwards were moving to the left side. But it is a very important lesson for us to consider having a pure RW in our squad.
We could force LW to play as RW, but I'm not feeling sure they're always feeling confident to leave from their actual position.
Madrid's main problem now is Mbappe. There is no doubt that Mbappe is a fantastic player, but I'm still saying this. Mbappe is a bit monotonous. And because of this he is not able to adjust himself well with the squad players. Also Vini and Mbappe have played in the same position in the past. So the players are having some problem to adapt to the new position. But since Ancelotti is a very experienced coach. Very soon maybe he will solve this problem. And we'll see stronger gameplay from Madrid next.
Mbappe's still relatively new in La Liga, and this probably makes him struggle to adapt to the harder league compared to Ligue 1. To be fair, Mbappe was fantastic in Ligue 1, but he is still unproven in the superior league like La Liga. I'll be glad if Mbappe has cr7's level of impact, but for now I can't see it from him!
I don't even think Mbappé will score more than 20 goals this season. This is because La liga is not league 1.
