Ancelotti must trust more senior players to play as starters in several matches, the experience of Modric and Toni Kroos can help the development of younger players. Young players have power and speed, while senior players have a lot of experience. This collaboration of players from different generations can create a more complete squad and help form a more solid squad.
I think maybe Ancelotti will definitely do a collaboration that brings together young players and old players in Madrid, in the end if he really doesn't have many players or is injured, I think Modric might have a lot of experience in Laliga but it seems he is still not needed for that and getting playing minutes for Madrid even though he has the desire to retire at Madrid, it seems that young players are currently being used more.
Every footballer always has a period of glory so Modric must understand that, if he doesn't get minutes, he will definitely be used later if many players are injured and we must also understand Ancelotti's goal of not using it, perhaps to keep Madrid on the winning track so that can more easily pursue the title this season.
