I really like Lamela and want him to become a superstar like Kane for us so bad! When he signed, all my FIFA careers I chose him because in my eyes he was a superstar who we managed to get because we were lucky. There's the Argentinian nostalgia connection as well which gives him a soft spot and he's done some spectacular things for us like the Rabona.
But overall, if we rank our attacking players for the past 3 years, it's clear that Lamela comes after Dele, Eriksen and Sonny. And the obvious reason is that Lamela has not been consistent and has been injury prone pretty much throughout his stay.
So I have no idea why certain people look at him like the second coming because even at his best, I don't think he was better than Dele, Eriksen and Sonny at their best.
It is wishful thinking that he finally reaches his potential and if he does, it is absolutely fantastic. But if 4 years have shown us anything, it is that he will manage a few decent games, pull off a spectacular one game and then get injured and disappear for a while. So I think we seriously need to get a player to challenge Lamela's position in the squad. Obviously GKN is so much worse than Lamela. So if we still hold on to Lamela, it doesn't matter. We need someone to challenge Dele/Eriksen/Sonny and in my eyes, unless Lamela pulls a miracle, it will not be him.
