Assists are the shittest stat in football mate, just take a look at van Dicks for Liverpool against Everton (Aurier's yesterday, it was just a 10yrd pass).
I said I think Sane is a quality player, but he's not performed to Son's level, he's seen as a weak link by both his International Manager and also by Guardiola who's admitted he isn't entirely happy with his attitude. he isn't as versatile as Son, who can play across the 3 behind the striker and as Striker. Line them up against a wall in the playground and I'm picking Son over Sane every game.
