Jose Mourinho may be a world-class boss, but he may need to work on his man-management skills.
The Portuguese manager doesn’t hesitate in publicly criticising his players - or exiling them altogether (see Bastian Schweinsteiger).
And there’s one player at Old Trafford that appears to have been criticised on numerous occasions this season.
After being substituted during United’s 3-1 defeat to Watford, full-back Luke Shaw was given a tongue-lashing on the away side’s bench. Then, after the match, Mourinho criticised Shaw for Watford’s second goal.
“Today for the second goal, (Nordin) Amrabat on the right side, our left back is 25 metres distance from him, instead of five metres.
“But even at 25 metres, then you have to jump and go press. But no, we wait.
“This is tactical,” he snarled, “but also a mental attitude”.
Mourinho questions Shaw's attitude
Mourinho, once again, slammed Shaw following his side’s 3-1 victory over Swansea on Sunday - but it wasn’t for his performance.
“Luke Shaw told me this morning that he was not in the condition to play, so we had to build a defensive line,” he said.
“There is a difference between the brave, who want to be there at any cost, and the ones for whom a little pain can make a difference.
“If I were to speak with the many great football people of this team, they will say many times they played without being 100%. For the team you have to do anything, that is my way of seeing [things]. Of course, it is not just the players, it is the players and the people that surround the players.”
To be fair to Shaw, he is still returning to full fitness after suffering a horrific broken leg last season and withdrew from the England set-up earlier this campaign due to a related pain.
Shaw is 'bewildered'
And now, The Times have revealed how Shaw feels about Mourinho’s latest criticisms.
Their report claims that the former Southampton player has been left ‘bewildered’ by Mourinho’s comments about him withdrawing from the match against Swansea. He's confused that his boss has singled him out for refusing to play for his side, despite suffering from a genuine injury.
Mourinho on Shaw's move to United
But it’s not just during his time at the Theatre of Dreams that Mourinho has criticised Shaw.
After the defender moved to United as a 19-year-old for £27 million on £130,000-per week, the then-Chelsea manager questioned the transfer.
“If we pay to a 19-year-old boy what we were being asked for, to sign Luke Shaw, we are dead,” he said.
“We would have killed our stability with financial fair play and killed the stability in our dressing room.
“When you pay that amount of money, the next day, we would have had players knocking on our door.
“They would have been saying, ‘How is it possible I play 200 games for this club, won this and that, yet a 19-year-old comes here and gets more money than I get?’”
Shaw may have a troubled relationship with Mourinho but, according to club legend Paul Scholes, the 21-year-old has the potential to be the best left-back in the world.
He really needs to sort out his differences by his manager before he can start fulfilling his potential, though.
