Anthony Martial came off the bench to be Manchester United’s match-winner against LASK on Wednesday night.
The Red Devils were lacklustre in the dead-rubber last-16 tie at Old Trafford having carried in a 5-0 aggregate lead from the first leg.
They trailed in the second half before a Jesse Lingard equaliser levelled things up with just over 10 minutes remaining.
And Martial completed their comeback just two minutes from time as he found the back of the net - just as he promised.
After the game, manager Ole Gunnar Solskjaer revealed the French forward was “begging” to come on - and he vowed to get on the scoresheet if the manager obliged.
Solskjaer said after the game: ”We needed to win the game. Of course, I wanted to but I couldn't get all of [the substitutes] on.
“We want to win and Antho was begging to come on. But he promised a goal as well, so well done!”
Martial’s attitude was typical of the approach he has shown at Old Trafford this season, which has also drawn special praise from Solskjaer.
"Anthony has upped his work-rate," Solskjaer said. "He's working harder in training, he's working harder in the games; his physical stats show that. He's been an absolute joy to work with.
"His attitude has been spot on and him and Marcus have found and hit off a really good relationship.
“And with Mason and Bruno coming in, that's improved us creating chances, the team's creating more chances. And tonight great link play with Juan [Mata].”
The Red Devils will now head to Germany for the final stages of the Europa League where a clash with Copenhagen awaits in the quarter-finals.
Solskjaer added: ”We'll make changes but now we travel to Germany with a squad that's had enough game-time. These players needed to play tonight to get their rhythm, get their confidence up, get the feel of a game. It won't be the same team [against Cologne], we'll make some changes.
"It'll be a mini tournament. The rules and regulations of the bubble that have got to travel, we've got to stick together and stay together in the hotel and the training ground. Let's see how long it lasts. Hopefully more than two days, hopefully up to 12 days.
"Everyone's going to travel on Sunday morning or Saturday night and we'll stay together as long as we're in the tournament."
