Mourinho's explanation in full -
“Because McTominay is working hard every day, he is feeling good and strong, he played the last match for 90 minutes and Paul last Saturday wasn’t able to play and this is the kind of game where I think a player must feel 100%.
“We are going to play with 3 midfielders and Paul can play in one of the two roles where Herrera and McTominay are going to play.
“Paul created some doubt by not playing on Saturday by his own decision, he was not feeling good and that created some doubt.”
Looks like Pogba had refused to play very late on and Jose is punishing him for it. There is definite tension here, it has come at the wrong time of the season for us. Think if we dont win, there will be leaks from Pogba's side about playing under mourinho etc. Really bad timing, i thought our squad rebuild was going on great, the club was moving in the right direction, this is a big speedbreaker on that road.
