This condition should not make us worried. I feel confident that Mbappe will be another option for Ancelotti to get variety in the game. Indeed, Mbappe's position is the same as Vini's, but I feel confident that Ancelotti is able to play them together in different positions. Because Mbappe is certainly able to play well not only in 1 position. Maybe he can be a central striker, or a main striker. Maybe he can be like Ronaldo. Being the main striker and opening up a lot of space to attract defensive players.
The competition between the forwards will of course still occur in order to be able to get a place in the Madrid front line later, Vinicius, Mbappe, Rodrygo, Endrick and Guler, of course must be ready with the fierce competition that occurs, but with the appearance and also the consistency shown by Vinicius in the last few seasons, of course he will get a guarantee of a place in the Madrid main squad, Likewise with Mbappe who does come with the status of a star player, of course he will also get a special place in the front line, so indeed this may make it difficult for Ancelotti to choose other players to also be able to get a position later, but even so, of course Ancelotti knows which is the best for his team and tries to get a really ideal line-up for him to use in the next season.
After the departure of Ronaldo and Benzema, of course, Madrid no longer has a central striker and they often rely on the wing as an alternative attack to the opponents defense so far, although they previously had Joselu but I think he has not been maximized as a target man in the front line and that's why Ancelotti released Joselu to the Qatar team, Mbappe who often played in the wing position when at PSG of course will most likely be plotted as a central striker, So that way Madrid will have the stability of the front line while still being able to endanger the opponent's defense.
