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.
The injury issues was one of the things that affected the performance of Real Madrid followed by the arrival of Mbappe that also made the formation of the team became unbalanced cause the manager couldn't find a perfect position to place him, Vini Junior was also frustrated because of the issues with some football fans and supporters who were against his attitude a lot of pressure was on him that made him to focus more on creating the scoring opportunities for Mbappe to do the finishing. Vini Junior never stopped being a good player the new manager needs to put things in place for him by that he should encourage the players to work together then people will see how great the combination of Vini Junior and Mbappe will become next season.
tIt is true that the imbalance of the team and the injuries have caused Real Madrid to be in such a bad situation. I agree with the two elements you mentioned. This is because I watched most of Real Madrid's matches last season and saw the weaknesses in these two aspects. That is why the team's managers have had to face a lot of criticism. The worst situation was the experience of losing to weak teams and the failure of all the great forwards to score goals. Despite Vinícius being an attacking forward, I was disappointed with his performance at times because his pace was decreasing and he was nowhere to be found in terms of scoring goals or assisting goals. It would be a surprise if Real Madrid can provide an impressive performance for the fans who are waiting for the upcoming season because they have constructed team with players from the previous season.
