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
In my opinion, everything is clear in La Liga, Mbappe must make his contribution to the Champions League, Real dominates in La Liga even without him. But I hope that in La Liga Mbappe will change the picture that we have seen in recent years - the top scorer scores 24 goals (this season, and last 23) and does not claim the golden boot. This is unusual for La Liga.
