Manchester United will face Tottenham in an all-or-nothing Europa League final after substitute Mason Mount's magical brace helped secure a 4-1 comeback win against battling Athletic Bilbao.
Last week's fantastic 3-0 semi-final first-leg win at San Mames put the Red Devils within touching distance of a return to Bilbao for the May 21 showpiece, but Ruben Amorim's side rarely do things the easy way.
Mikel Jauregizar's 25-yard strike gave Athletic a deserved lead as United stumbled out of the blocks at Old Trafford, capitalising on an error by quarter-final hero Harry Maguire's error in spectacular fashion.
The Old Trafford faithful stuck with their stuttering side and Mount's excellent turn and strike punctured growing tension, with Casemiro's header and a close-range Rasmus Hojlund effort completing the turnaround.
And Mount scored a glorious second from long range in stoppage time, with goalkeeper Julen Agirrezabala well out of position, wrapping up a 4-1 victory and 7-1 aggregate triumph.

United boss Ruben Amorim said his side's win over Bilbao will mean nothing unless they beat Tottenham in the sixth all-English major European final on 21 May.
He told TNT Sport: "It's the least we can do for all the fans for all the support they gave us in this tough season. But I'm stressed already because of the final because if we don't win it, in the end it's nothing.
"So we are happy to be there. Let's see. I can see I should be a better manager at this moment, the team should be better at this moment, but we are trying and I think we did quite well in Europe. We struggled a lot in the Premier League."
Amorim also had special praise for Mount for his two superb goals after he stepped of the bench in the 62nd minute .
The Portuguese added: "I'm so happy for Mason Mount. He's such a player. He works really hard, he has quality. Sometimes you are on the bench and you change the game."
