You know, Real Madrid has no striker, they finally find out the missing puzzle by signing Mbappe. So, it is no problem at all by having Mbappe.
Having many quality players is good because it will make Real Madrid to perform well. As long as there are no many players who compete with a certain position, there is no difficulty to face by Ancelotti. Mbappe is the only striker in Real Madrid, he even has no competitor. Even Real Madrid signs Joselu or another new striker, Mbappe still can be in the main lineup because Mbappe can play as a winger.
Real Madrid have a comfortable environment in the Spanish La Liga. After Benzema left, instead of signing a good striker, they made do with the good performances of other players. But I don't think they could have done that in the English Premier League. Also, we must not forget that Barcelona are in a weak period. So everything was a little bit easier for Real Madrid. Normally they could have finished last season with worse statistics. I think Mbappe likes to play on the wing more. Because playing as a wing forward creates more free space for the players. I hope Mbappe will be happy to play in the role of the team's striker. Because it will mean more responsibility for him.
