I think it's pretty obvious that this is not a football decision Pogba is facing. Our project is miles ahead of United's.
It's basically down to if he at such a young age can turn down the amount of money they're offering. And lets not be naive, they're a bigger club than us and that league is more marketable, so he'll make more money off the pitch as well.
The best move for him football-wise imo would be staying with us or join Real. Money-wise United looks stronger than even Real at the moment. Tough decision for Pogba, lets see what happens.
