The 19-year-old complimented an ebullient display at No.9 with a truly sensational free kick into the top far corner after 67 minutes to hand Mourinho’s men the advantage ahead of next week’s deciding clash at Old Trafford.
He hobbled off after 80 minutes to be replaced by Anthony Martial, exchanging a few words with Manchester City reject John Guidetti as he did so.
And Mourinho, speaking after the game, noted that Rashford was harbouring a slight knock heading into the game.
“He’s a 19-year-old kid in love with football,” he said.
“A kid that finishes the training session and stays half an hour more for free kicks so it’s just mentality.
“He works and works and works, he’s very mature, let’s forget the age.
“He started the game with a little problem and obviously with the running and continuity – Martial was fresh and we thought we could still score because of plenty of space to play so we tried until the end to win.”
Supporters will desperately hope that Rashford’s withdrawal from proceedings was strictly precautionary. The very fact that he was able to play with this “little problem” in the first place suggests that the affliction is by no means threatening.
United have reached a stage in their campaign where slight knocks are not sufficient for sidelining the limited options Mourinho has at his disposal. With the season entering its climax and injuries continuing to pile up, the Portuguese will want to see his players play through pain – to throw everything at the cause and worry about the physical ramifications later.
And one suspects that Rashford will be raring to go once again after what was another scintillating display at No.9 in Galicia.
