Every year since Pogba's arrival there is endless debate whether or not Pogba is a world class performer, worth what we spent on him and his wages and so on, but the fact that no other clubs have even tried to take him away from us really does say it all.
If he was as good as we were expecting him to be when we purchased him, Real, PSG or Barca would have at least tried to get him, especially with the Zidane/French connection to PSG/Madrid or Barca due to their need for good midfielders, but instead got De Jong.
Pogba's not a bad player by any means, but he is not the world beater we expected, or needed, when we bought him. His defensive and concentration lapses are way too common to play deep and he doesn't provide enough goals or assists to play behind the striker which has caused us issues very, very regularly. This was apparent when Bruno arrived and in just a few months provided more actual end product than Pogba has for 18-24 months now.
Unsure if it's all due to lack of motivation because of how poor we've been since his arrival, the Mourinho fights, or what - but he hasn't lived up to his price tag, and anyone who thinks he has is probably in denial.
If he has a good season and goes into next summer window with one year left on his contract, he's certain to force himself out I think. He was never loyal to Manchester United in the first place and won't have a reason to stay next year, unless we pay him silly, silly money.
Let's not forget who his agent is, either.
