I still think he's gone. Not something I'd criticise him for as it's his career but just doesn't strike me as someone who wants to stay at one club for too long.
Only things that might change it is if he's maybe tempted to stay now it seems like the club is actually building something, and maybe the market pricing clubs he'd fancy out of buying him.
If it's the later though I'd expect more sillyness particularly from his agent.
Pogba is 27 years old and has only played for two clubs which is a small number among footballers. So I'm curious to know why he doesn't strikes you as someone that stay at one club for too long when Pogba's career isn't even close to show that.
