Alvarez is a fantastic talent and ready to play a part for us - in the middle.
He came through at River Plate as a winger and was regarded as a good young player with decent potential. But it's only when he went through the middle that he exploded. He's a fantastic finisher, good with both feet, he presses well, he's stocky and strong and he's not slow. But he's probably not as fast as Jesus and certainly not as fast as Sterling. Alvarez is Gabby's replacement, pretty clearly - a back up striker who can also cover the wings and press. He isn't at the same level technically but he could end up being a world class centre forward, and a very good inside forward.
He isn't as good as Gabby on the wing, and Gabby isn't as good as Raz on the wing. The idea that Alvarez is a suitable replacement for Sterling is nonsense.
If he's going, fine. Get the best fee and get it done. But if we've got to within a year of his contract running out and we haven't identified a suitable replacement, it's a failure IMO.
