The strength is in Real Madrid and not in individual players like Bellingham and Mbappé. This is why I will always give the flowers to Vinicius junior because he has done marvellously well in Real Madrid. He defended and maintained the reputation of No 7 which Hazard failed to uphold. He was an instrumental to Benzema winning Ballon d or in Real Madrid. He has paid his dues and I think it is his turn now. Even when Madrid is on low, he will surely find a way to raise the velocity.
You can check the individual performance of Jude and Kylian and even Vini in the Euro and Copa America, you will discover that the strength lies in Madrid and not individual players
The Real Madrid team has a fairly solid framework which is aided by equality of quality in all lines so that this team does not depend on just a few players, and this is not only in the current era but has been like that for a long time.
And individually, I think Jude, Vini and Kylian Mbappe are not much different and it's not that important, what's most important is how these players can work together in a team to create or help improve the team's performance.
And Real Madrid is one of the best teams in the world so playing at Real Madrid is also the dream of many of the best players so it is not surprising that they always manage to get the best players.
