It's time to find out how well Jose Mourinho really knows his Manchester United players.

After being announced as the face of Heineken's new Champions League campaign 'The Prep Talk', COMPLEX caught up with Jose Mourinho in Manchester and asked him for his opinions on a handful of Old Trafford talents – the only catch was he had to identify them from their childhood photos first.

Speaking to COMPLEX on his feelings towards their major summer signing, Paul Pogba, Jose said:

"Paul is one of the happiest guys I’ve found in football, that was my immediate impression. He’s a guy in love with life, in love with who he is and he enjoys so much being the star that he is. He’s a great, great boy."

It's time for Pogba and his teammates to start putting in the performances that will make Mourinho smile, too.
