Ansu Fati, a striker once considered a prodigy and expected to replace Messi at Barcelona. Miramontes once praised him and said that Fati would be a worthy successor to Messi's number 10 shirt. But injury brought his career at Camp Nou to a dead end. He gradually lost confidence when he got another slight damage, and coach Xavi dropped him from the main squad. In particular, the appearance of Lamine Yamal forced Fati to sit on the bench. Brighton borrowed Ansu Fati until next summer's transfer window. This is an opportunity for him to once again prove his achievements.
I think Barcelona has a bit of a trouble about Messis past. I mean whoever is the new player that is coming out of the youth side that looks even just a bit of good, gets the name "new messi" and we all know that is not that possible, we are talking about one of the greatest to ever do it. This is why we shouldn't really consider any kid that good, it is unlikely and it will probably not happen.
I think it is important to make sure that we are talking about a decent level player, that's it. If you tell the kid that he is the next Messi, and even give him the jersey number, then you are going to be losing a lot of confidence when he doesn't play like that. At the very least, it looks like they got their new iniesta and xavi with pedri and gavi.
