That's true he's among one of the players that's helped to be successful In his time the last time they won the league and even the Champions League he played a vital in Real Madrid achieving those trophies although Madrid poor performance last season affected him but that doesn't mean he's not a good player.
Last season's poor performance had several issues, one of which was the increasing number of injuries. Meanwhile, Mbappe arrival also created a different impression, as Vinicius seemed to be no longer performing well. However, people forget that Vinicius simply provided an opportunity for Mbappe to score more goals and adapt quickly. Had Mbappe not arrived at Madrid, Vinicius would still have been known as a great player last season.
I don't know if some players are having a negative impact on Real Madrid. The team had a lot of potential to improve after Mbappé joined Real Madrid but instead it has been the opposite which is attributed to the internal conflict in the team. Mbappé is scoring goals regularly but Vinícius is not doing better and he should be playing better football. Star players like Rodrygo and Bellingham are not performing to their potential. Injuries to some of the best defensive players and the absence of coordination within the team have only reinforced the gossip of infighting within the team.
Exactly, the kind of player Real Madrid has and seeing they didn't do well last season and even wavering currently is something I don't expect because they had all it takes to do great in all competition. Vinicius, Mbbape and Jude Bellingham are the kind of Frontline every coach will wish to have but I later realized that sometimes squad is not really what a team need in order for them to do great, having a squad without cooperation and coordination is waste because there won't be oneness and unity and everyone will be playing what comes in their mind.
You are right, Madrid has good players and for them not to perform well last season was something that shocked everybody however I will not say they did not perform well entirely they try their best, even though they did not lift any trophy last season however since they have a new coach now I believe things will change, the New Coach should just know how to use the star players in Real Madrid very well if he can use them very well they will lift a lot of trophies next season, mbappe, vinicius Junior and Jude Bellingham should work together in order to lift trophies.
If mbappe, vinicius Junior and Jude Bellingham refuse to play as a team then they will keep having problem in their team one thing I believe is that if they are too much star players in a particular team they will hardly play as a team however if they agree to play as a team they will surely win trophies and be the best team in the world, the New Coach should do his best in making sure that real Madrid becomes one of the best again because that is what they are known for.
