LOL.
This is nonsense!!!
Barcelona already has a great squad including Lamine Yamal as Barcelona's Messi, so what do we need from Messi? He is old and can't run fast anymore while in LaLiga the game is tight.
This rumor is too far from valid, he will stay in MLS for the rest of his career.
Funny when I read this particular sport news, first I thought it will be believe able then my second thought, this is some kind of random rumor that needs to ignored. Barcelona already have some kind of competitive and formidable club, more focused on winning titles, checking their statistics, the club is doing really good and they don't need the services of Leo Messi.
Hansi Flick is more concerned on becoming one of the best things that will happen to Barcelona this season. He has other plans for the club and wouldn't jeopardize that because of some random intents of bringing Leo Messi, he's satisfied with his current squad and he's this type of coach that's very much interested in young players.
