I disagree, 100%. If a player was laughing in the stands whilst his team lost at the likes of Bayern Munich etc, then they'd feel the wrath of the fans and the real footballing guys at the top that genuinely love the club and would consider themselves supporters too. Just because we have a chief exec that wants big names that sell shirts and get twitter likes at his new Disney Land franchise, no matter the cost or how they conduct themselves, doesn't mean that we should accept it.
I'm not going to say we should sell him, because I don't have a clue what's happened behind the scenes, as do you. But if all of Pogbas 'accidental mistakes' were done on purpose, then I'd convince the Glazers to sell tomorrow no problem. No manager can operate whilst being undermined by a player, who is in turn defended by those higher up. What are you supposed to do when they aren't following orders on the pitch or are stirring up trouble in the media? What would you do if you were managing Pogba and he was making a mockery of you every day (hypothetically)?
Interestingly there have been reports that claim we will now sell Pogba in January. If that's true or his 'messed with the wrong baller' story is true, then it doesn't look good for Pogba.
And just to point out, an ideal world outcome right now for us is that Pogba starts performing like he's capable of. United play well, the players are happy and we can all laugh at Pogba and Lingard dicking about. And hopefully Jose has been the one instigating all the media to go against Pogba, though I doubt he has the likes of Paul Scholes in his pocket.
