The Portuguese handed the supporter his suit jacket in the aftermath of the game at Old Trafford, only to see it whisked away from the fan by a security guard, report the Manchester Evening News .
The official checked the pockets for any valuables and handed the garment back, as the fan went on their way with a unique keepsake.
But while the Red Devils boss left one supporter happy, he failed to partake in an Old Trafford tradition when he didn’t deliver an end-of-season speech on the pitch.
Sir Alex Ferguson would address the crowd following the final home league game of every season, which would accompany a lap of honour from the players.
Even Ryan Giggs followed suit in his role as interim manager when standing in for the sacked David Moyes in 2014.
Louis van Gaal continued the tradition in each of his two seasons at Old Trafford.
But Mourinho, who held a bizarrely brief post match press conference on Sunday, chose not to take to the microphone ahead of Wednesday’s Europa League final.
His squad did, however, compete a lap of honour before beginning their preparations for Stockholm and the game against Ajax.
Mourinho was clearly in a hurry – even cutting short his interview with in-house broadcaster MUTV.
Despite the upbeat end to the domestic campaign, Mourinho was in a brusque mood with United’s in-house channel MUTV.
“Don’t ask me too many things because now I am in a final,” he told commentator Stewart Gardner. “Let me go home, I am in a final now.”
Gardner replied: “Do you know your team?”
Mourinho merely replied: “I know, but let me go. I am in a final now.”
