I am not against signing Fatu but there must be "something" going on behind the scene that we're unaware of. Yes, injuries has been part of his lack of development (he was once seen as the direct replacement of Messi and one of the most promising talents in the world), and right now he's behind Raphinha, Lamine Yamal, Ferran Torres and Abde Ezzalzouli in the pecking order.
But if Spurs sign him on a loan deal and he turns out to be a decent-to-good player, it will help Angelos and Spurs to buy time and look for more suitable and affordable (L & L still control the purse) players rather than panic buy.
