Regarding player recruitment, of course Real Madrid is the team that is best at doing it. No aggressive in buying lots of players, but one purchase can outperform any team in La Liga and Europe as a whole. This season by only having 1 striker like Mbappe, we can easily judge that Madrid stability next season will be much better. Mbappe doesn't need long to adapt, but even if he need this is the right time. Mbappe will remain focused on the national team, so we cannot see any developments regarding Mbappe with Real Madrid. After the Euro everything will become clearer because there Mbappe will be officially introduced.
Before now there have been an official statement that the Madrid deal and mbappe was confirmed a done deal, I don't think for such player, Madrid is going to probably let him stay long before he starts to fully play because they want him adapting to their system or pattern, I believe mostly it will be that since he's answering to a national assignment currently, he may be given a break awhile just before he officially begins his duty officially at Madrid.
Mbappe is one of the best signing Madrid have made this period even if he's yet to start playing to show his performance but Many are confident in him already.
I believe
