I hope he has a good European Championship to boost his price before the next summer window. I don't expect him to play well consistently for United, so a brief burst of good form will mean a lot to his transfer price.
Pogba evidently cares more about international football than Manchester United. Which is fair enough for him to do as a human being. But Manchester United, as a football club, need to recognise that Paul Pogba is only as good as the desire he puts into his performances. If that desire is lacking whilst he wears a red shirt, we need to get rid.
It's an obvious thing to say, but an employee who loves and respects his employer is going to work harder than somebody who doesn't. I know that I've been guilty of the same thing when working in the public vs private sectors. In football, that's an attitude you can't hide when there are a dozen cameras on you every second you're on pitch. Pundits and fans have been saying it for years. It's clear that Pogba gives United less than he's capable of. I don't believe it's something that can be fixed, so it's best that we part ways.
Blame the manager or his teammates if you want. But it doesn't excuse his own poor work ethic,his own lack of responsibility and his own dereliction of duty. Let's just say, I doubt he'd have been caught wearing a Juve shirt if he were a Real Madrid player.
