No need to bet anything on that. The style of play and the grinta Pogba has, are just made for a club like Juventus. He already showed it there, and I bet if he goes back, he will be even better with the experience he now has in England.
This is a player for a team with very physical play combined with technique. And that is far from what Manchester United's style of play is right now. Go back, Paul, and with Ronaldo, you'll win the Champions League!
