Yea, it is a blessing for mbappe to join Real Madrid. As you mentioned, Real Madrid is one of the best teams in the world right now, which is the truth. mbappe will also enjoy his stay in the team, and that will go along way in seeing his progress in his football career. but with time he will adopt with the team and be a great achievement for him because playing in Spain will not only improve his career but also have a positive impact on his lifestyle, although we all know that France is different from Spain, so with time we should expect a new mbappe, which I am sure we are going to see many incredible things and styles from him.
Playing for Real Madrid have been Kylian Mbappe's dream right from when he was still a kid and now that he finally got the opportunity of representing the club, you should always expect him to give his best to the club. One of the reasons he also decided to join Real Madrid is because he's yet to win the UEFA Champions League trophy and for a club that's won it 15 times in their history, playing for them is the surest route to become an European champion.
In his first game for Real Madrid, Kylian Mbappe was able to win a European trophy for the first time in his career and that I think tells how fulfilling he feels already to be part of the club. For many of us that loves the footballing prowess of the France international, it was sad to see him struggle to find his feet in the Spanish La Liga but now that he finally got his first two league goals in the league, I'm pretty sure that he'll continue to be score plenty more in games to come
