Endrick, Vini were Messi fanboys before signing up for Madrid. Bellingham, Musiala & Davies and there are lot of other players that look upto Madrid. OP needs to check on those players who are either playing at different club or had no affiliation being a madrista as growing up. You will see the big picture, the names you mentioned are madristas except Saka and the name i mentioned are not Barca fans but they idolize Messi 👍🏻
