mbappe is a player with great quality, just remember that mbappe carried the entire French national team in the last world cup
Mbappe is a good player and one of young super star players recent years but I disagree to say he carries his teams like PSG or France. He needs support from his coach who uses him at proper positions on field, and his team mates who will provide him space and key passes, assists.
while when you look at Jude Bellingham, Vinicius Junior and Toni Kroos are not players who carry the entire national team from their countries, this is the big difference that exists between these players with mbappe.
Again I really disagree, these players are important and they have good contributions for their teams from clubs to national teams. I have to bring a very old lesson from Real Madrid, 20 years ago, when Perez with his Galaticos 1.0 plan. He decided to sell Makelele to Chelsea and we knew that with Galaticos 1.0, their squad is very weak in defense after they did not accept request from Makelele and let him go.
Mbappe will need not only support from attacking players in Real Madrid but will need good performances from defensive players there. Because a team can not have good ball possession and are able to attack well if their defense system is weak.
