Just knowing the clubs involved, this absolutely screams FFP scam or something like that. I would guess the structure of this deal would basically guarantee he'd go back to Barca for a slightly higher fee in 2/3 years and we're both happy.
It just doesn't make sense to me, he seems too rated by Barca, also seems like a mad move for him to agree with and who knows if he'd even play. It's Moise Kean all over again but in fairness that deal did suit us, seems bizarre though. Like, let's say this is a fully legit deal with no dodgy business, why would we target him? Brazilian wonderkid forwards for big money are not the market we shop in.
