Mbappe has just joined the Real Madrid team and he has not found a strong chemistry with his teammates so I think Mbappe needs time to adapt and there is nothing wrong with that.
And for Real Madrid's performance which is currently struggling because many of their main players are injured so that it has a big impact on the performance of the Real Madrid team which is declining and inconsistent.
In terms of individual quality, Mbappe is quite good, no one doubts it and he needs time to be able to contribute greatly to the Real Madrid team, I'm sure that will happen.
There are eight Real Madrid players who are still injured including two goalkeepers and that really puts Real Madrid in a difficult condition because the team must be able to work hard before the eight players recover. As for Mbappe, he only needs players who can give him the best passes so that he can finish well into the opponent's goal in every match that is still there this season. If Mbappe doesn't get that, I don't think anyone should blame him for any reason because he also needs good teammates to pass to him every time there is an opportunity.
Mbappe recent performances have led to growing frustration among fans and talk of a tactical change within the team even though Real Madrid have a comparatively higher number of star players than other teams. Carlo Ancelotti is currently in charge of the team but he is not able to make the team perform well. In July Mbappe was introduced to Real Madrid in an official introduction session and went on to make 11 appearances and score 7 goals, but former England coach Capello has advised Mbappe to work harder if he wants to score more goals in the coming matches. Capello previously coached Real Madrid for two seasons and knows Real Madrid very well. In an interview with a Spanish media outlet, he said that Mbappe along with his teammates, will have to work harder.
