The Real Madrid team has been strong since Pati but this season Mbappe has become even stronger due to the addition of Mbappe to the Real Madrid team. And this season will always be top and i can say manchester city can take second place and real madrid is likely to take first place. There will be a huge fight in the points table.
Mbappe just had a 5 years contract with Real Madrid, and he hasn't featured in any of the Real Madrid matches(Champions League or Laliga). To that, We don't know how his performance with Real Madrid will look like "good or bad" but we just hope it will be a fantastic one that keeps Real Madrid more formidable as they already are to lift the Laliga and Champions League trophy once again in the upcoming season
There is no way that his performance is going to be anything but spectacular as long as he can remain healthy, in my opinion he is the best soccer player today and he will be surrounded of the best players around the world too, if anything this is a move that could create a dominance that we have not seen in a long time and it could create a historical run for Real Madrid, which is why I cannot believe other teams did not do the best they could to avoid this transference to happen at all.
