Always the body language experts
He got injured during a game, stayed on the pitch and was limping but still tried to make a run without the ball at the very end of the game to win the game... but yeah his body language tells you that he doesnt want to be here or that he isnt trying his best.
And ofcourse he would like to leave.
He is too good to play in this team and i cant imagine that he likes being the scapegoat for everything that goes wrong.
Rashford, Martial.. even Shaw, Young and local boy Lingard would likely want to leave if a club like Madrid wants them and can offer them a chance at winning the league but always play CL and a chance at winning the CL. No other clubs wants those players though... clubs do want Pogba because he is actually a very good player.
