I find with Pogba it is best to ignore everything he and his agent says because they either court headlines, or he (not his agent) is misquoted to fit a dramatic narrative. Only ever interested me what he did on the field.
With regards to his contract, I think it is time to play hardball. We definitely shouldn't be losing him on a free, and anyone who says he isn't a good player is nuts. We should be offering him a 4+1 deal on generous terms and tying him down, at the very least agreeing to let him go for a reasonable fee if he wants to leave. If he and his agent don't agree to that, and are determined to leave on a free, we should heavily limit his game time next season before a world cup year. It's the only leverage we have.
I still rate him as a player and a person. but the influence of his agent remains toxic.
