The arrival of Mbappe and Endrick has great potential to make Real Madrid even stronger but on the other hand, this will also make the battle for places in the first team even fiercer (particularly on the front lines). If Arda Guller ends up staying with Real Madrid next season, then he will also be in that fight. Obviously it won't be easy, because he has to compete for a place against Vini, Rodrygo, Bellingham, Mbappe, and Endrick.
This condition might also be a headache for Carlo Ancelotti because it's not just about determining the best decision but he must be truly transparent so that the decision does not give rise to assumptions among the players that might actually trigger jealousy and unhealthy rivalries.
I don't think Arda Guler needs to fight with these players for his position because Arda Guler is a midfielder and not a striker. So it really doesn't make sense if he competes with these players. In addition, Arda Guler must be able to compete with other midfielders such as Bellingham, Camavinga, Modric or Brahim. However, of the four names, only Brahim could take over his position.
Arda Guler doesn't need to compete for the first team because there are no longer any players he can replace, but if he becomes a more proportional backup like Brahim, he might still be able to fight. On the other hand, if a midfielder is injured, it will also give him a bigger chance to play. So this is just a matter of rotation so to fight for the main place I think it's still quite a while Arda Guler can do it.
Wow, Endrick is still very young at 17 years and as such, of course it will be difficult for Endrick to be included in the starting eleven. Therefore, it looks like Endrick will be on the bench more often and even though there is player rotation, I believe it will still be difficult for Endrick to enter the starting eleven. With Endrick age being so young, I personally would be more confident that Real Madrid would loan Endrick to another team, of course to be able to continue to improve the quality of his performance rather than just sitting on the bench moreoften. But indeed,inthis way it is clear that Real Madrid is really making progress inthe long term because it recruits young players. Ofcourse, that is a very great way for Real Madrid to do it, because in this way Real Madrid will maintain its great quality from season to season.
