It's not possible to know, of course. How is the Pogba/Jose dynamic going?
Might Paul not be feeling the love, not being the best-paid/most written about player anymore, a lot of attention on the piano-tinkling new guy? It is possible to imagine that having some effect (awful if it has, but he is young, and human, and very egotistical and attention-seeking). If he did feel that way, other grieviances, like not loving Jose's tactical set-up (hard to blame him in this respect) might be made worse. But if anything like that actually was afoot, Jose showed no signs of it in his post match. He seemed calm, like everything was ok, just annoying how the mistake was made for the first goal. Like it was a decent enough performance, a kind of failed draw. Very different interview in tone to Conte's pessimistic, downbeat vibe. No need to over-react, yet, anyway.
