Last night Jose Mourinho guided Manchester United back to the Champions League with a 2-0 win over Ajax in the Europa League final.
And while the Portuguese boss has been praised for taking the Red Devils back to the big time with two major trophies in his first season in charge, he has come in for criticism in his dealings with some of his players.
Luke Shaw is a prime example of one player that has been publicly criticised by Jose Mourinho this term, while Henrikh Mkhitaryan and Anthony Martial have both received some stern words of advice over the course of the season.
But one player that has impressed Mourinho by coping with the pressure of playing at a club of United's size is Marcus Rashford.
The 18-year-old has contributed 11 goals in all competitions and led the line against Ajax in Stockholm.

Jose Mourinho admits he can't always understand players who have a fragile mentality
“He was, of course, a tornado, when he arrived last season without pressure. No responsibility. And this season when the pressure was on him, when he was not scoring goals for one, two, three, four months, he coped with that pressure. This is the kind of character I like. I like to squeeze the player and the player to cope with it and react to it.
"For me what’s more difficult [as a manager] is the fragile mentality.
“I think it’s probably my weakness as a manager, that it’s difficult for me to understand people with a different mentality to what I have.
"It’s difficult to understand so it takes me time to understand and sometimes I’m not able to feel attracted again [to the player].
“Sometimes I ask my assistants to help me on that because maybe they have a different profile to me. Because for me I want to be in love with the player with this character, with this personality and that kid Marcus is the best example of it, especially in this club.”
