Paul Pogba

The most widely covered player/manager feud has been Paul Pogba v Jose Mourinho. Both parties have denied any disagreement but numerous reports, as well as a viral video of the two arguing, seems to suggest otherwise. Last season Pogba was omitted from the starting line up of a crucial Champions League tie vs Sevilla and this season after giving the World Champion the captain's armband Mourinho took it away.
All these antics have been reported on endlessly but somehow Pogba's individual performances for the club have not been affected. The midfielder leads the club in goals and assists and has started every single one of United's Premier League and Champions League games.

The truth is we are together for two years and a couple of weeks and I've never been so happy with him as I am now, that's the truth. I cannot demand more from him,” -

Interestingly, the players who have disappointed the most this season are the ones who are rarely ever criticized by the self-proclaimed "special one".
