I've not said much on this topic.
But it would be a huge credit to him, and a massive feel-good story, if he actually buckles down now, works super hard on his fitness/injury record and wins Jose over. It would also add to our options in midfield to partner Pogba.
I can genuinely see how, being constantly injured/unfit and flying out of the country at every opportunity to go back to Germany or follow your wife around on tour, wouldn't go down well with the rest of the squad and now, supposedly, the manager. Even if he got the permission from LvG to do so.
He should have been more committed, especially as he's seen as a leader and senior figure, on fairly big wages. He might have earned such "leeways" at Bayern for his service, but coming to a new country, a new club trying to fight their way back to the top - that attitude simply wasn't needed. I'm not saying he was unprofessional (especially as he seemingly got permission from LvG) but yeah, the timing was far from ideal.
But yeah, imagine a team with Pogba, Ibrahimovich, a fit and injury free BFS in it
We lacked leaders a few years ago, but it's certainly not the case at the moment.
