I agree with that. Mbappé's arrival at the Santiago Bernabéu should further enhance Real Madrid's attack. Both players are top-tier players, and they should be able to work together for the team's progress. However, it's truly regrettable that Vinicius considers Mbappé's presence a threat to his role as Real Madrid's star. He refuses to lower his ego, which is why Vinicius' performance last season was quite poor.
The new season is about to begin, but Real Madrid's attacking issues haven't been completely resolved. A new star has emerged in Gonzalo Garcia, making the competition even tighter. Rodrygo is one Real Madrid player who lost out in this competition and is now on the transfer market. I'm eager to see what other players will enter the summer transfer market before the new season actually begins.
When such problems arises between players in same team it is the duty of the coach to find a common ground for them to come to peace with eachother by making sure they place the interest of the team above their personal interest. But this was one thing Ancelotti failed to do. However, Xabi Alonso's position as coach should be able to resolve all of those superiority attitudes between Vinicius and Mbappe. I would have suggested selling off Vinicius but at the moment Real Madrid needs him especially now they are having a worse era.
