United have found a run of form in recent weeks as Mourinho's influence begins to kick-in at Old Trafford.
The Manchester giants made a stuttering start the campaign as the Portuguese got down to business at his new club.
But they are now on an eight-match winning run in all competitions.
And Mourinho's influence behind the scenes has now been revealed.
Mail Online report Mourinho's 'challenging' training sessions were warmly greeted by Man United's players following his summer arrival.
They were said to have immediately taken to his ideas at the club's Carrington HQ - which were vastly different to the dull plans of predecessor Louis van Gaal.
It's also claimed players who have been called out publicly in press conferences have been happy with Mourinho's man management in private.
And the United boss getting involved in pre-match banter on the team bus to away games has also been well received.
Mourinho is said to be 'well-liked' for getting stuck into the jokes and high-jinks the squad get up to when travelling to games.
