Of course that's bullshit. Who is Lamine Yamal? To be honest, he's certainly not a bad footballer, but I've seen so little of him so far and someone is supposed to pay 200 million for him? That's a 100% lie, because Barca would sell him without thinking twice for 200 million. Even a Messi today wouldn't be worth that much as a newcomer at that age (assuming Messi is an unknown 16-year-old player).
To be honest, which one team interested for signing Lamine Yamal over 200 million euro behind many top players with much experienced on the top level performance available for signing above 100 million euro. I think its more bullshit underrate values for youth players without much experienced and not winning any tittle yet for this season, there are have many top players already with price over 100 million euro and some teams won't spending over 200 million for Lamine Yamal only because there are available to sign until three players with higher level performance.
I doubt with Lamine Yamal future will be the same the next Lionel Messi label put for Ansu Fati, finally he has leaves Barcelona and joining with Brighton Albion teams but can return to his top performance.
