United had lost out on the prize in a 2-1 defeat to Real Madrid in Skopje through goals from Casemiro and Isco, while a late strike from Red Devils striker, Romelu Lukaku kept the game competitive right to the end.
The Reds boss joined his team to collect his runners-up medal on the pitch in Skopje, but promptly handed it to a delighted supporter – a boy named Deji – in the front row before departing.
When asked about the gesture in his post-match press conference, Mourinho gave an answer:
For me, the medal would go to some place in my house; for that kid, it's the moon, something to keep and remember.
It was a little kid with a United shirt. I have no idea where he comes from. I think it's something he'll never forget. I repeat: when I win, they don't mean much, so imagine when I lose!
