That's where there is a main difference, Alvarez will fucking try, in fact like Tevez he runs his fucking socks off mainly every time he plays, where as your mate Jesus just frowns or rolls about on floor, hence why he is no longer with us, so there is no shock in store coming at all, he's a tryer, and his stats outweigh Jesus, simple as.
Pep said Jesus was one of the best in the World when it came to pressing, and repeatedly said it's unusual to find a top player who will put in so much effort.
Alvarez is a better finisher, but has less skillful close control, however I'd argue that in terms of being a 'tryer' they are probably two of the best we've had in the last decade.
