He got a shirt upgrade.
There is no evidence he wasn't informed prior.
If I arrived at work and found that my workplace had been taken over by someone & I'd been given an upgrade, I honestly wouldn't give a care. But these players are not office workers & have short careers where they move around a fair bit, so why would anyone get precious over a number on the back of a shirt?
Seems a lot of people are assuming he is upset with very little evidence, if it were Fellaini or Rojo, I'm certain fans would be less understanding.
He plays 11 for France without any issue, now we've matched him up. Lad should be well pleased. Had he not got a shirt number and been told he was training with the kids, then yes I'd have some sympathy.
