He wasn't that good last season, but a lot went on at Lazio last season. The previous year showed he has quality and could be a good addition to our squad instead of Oscar, Pedro, etc.
They have had a clear run at two players no other big club were after from the outside. Any Pogba deal will be funny and crazy at the same time for many reasons.
I personally would be shocked if he decided to return to the club that weren't willing to give him a chance (regardless of who the manager was). Mkhitaryan is supposedly going to earn £200k a week, so are they offering Pogba £400k+?
