According to that possible line up, Rodrygo might be the bench guy unless if Alonso decides to go with a different approach. Arda Güler seemed to be gaining much favor layely. Also, Alonso might lean more into 3 center backs so that whole back set up might change.
I prefer seeing what he will present in his first games before we speculate about the starting 11. Also, the transfer market is just getting started.
I also think Xabi Alonso will come with a different approach from what Ancelotti used in his time. I am also anticipating his first three games especially the pre season games when he officially becomes the club’s first team coach. Few days ago I read about Xabi preferred three centre back system but I am not optimistic that Xabi will bring a fresh system to the team with him.
