Paul Pogba scored the winner on his Manchester United return as they edged past AC Milan at San Siro to reach the Europa League quarter-finals.
The France midfielder settled the tie three minutes after his introduction as a half-time substitute with a composed finish from close range.
The 28-year-old was making his first appearance in the competition this season, after coming back from a thigh injury which has kept him out since 6 February.
Until his intervention, Ole Gunnar Solskjaer’s side had rarely looked like breaking the deadlock against a well-organised Milan team who also appeared capable of adding to the late away goal that had swung the tie in their favour at Old Trafford.
Rade Krunic, Alexis Saelemaekers and Theo Hernandez all threatened the visitors’ goal before the break.
Zlatan Ibrahimovic was summoned from the bench to try and rescue the tie, but United goalkeeper Dean Henderson superbly saved to prevent the Swede from scoring with a back-post header.
Henderson, who was excellent throughout, also brilliantly turned away an earlier effort from Saelemaekers.
United join fellow English side Arsenal in the draw for the quarter and semi-finals on Friday at 12:00 GMT.
Pogba makes the difference
Prior to this fixture, Solskjaer had stressed that winning a cup competition should not be used to determine whether the club had progressed since he took over in December 2018.
But after losing four semi-finals over the past 12 months, a defeat here would have left him facing serious questions over whether his players have the ability and mental fortitude to develop a winning habit.
With Manchester City out of sight in the Premier League, it would have also placed even greater importance on their tricky FA Cup quarter-final at Leicester on Sunday (17:00 GMT).
Pogba’s introduction and goal means they are still in the mix to win a competition that produced their last piece of silverware in 2017.
It was far from a vintage display and with Edinson Cavani absent, United appeared to lack nous at the sharp end of the pitch.
However, Pogba, who came on for Marcus Rashford, provided what they appeared to be missing in the first half – the guile, composure and good decision-making required to make a difference in front of goal.
Fred’s persistence unquestionably helped as the hosts missed the opportunity to clear their lines on more than one occasion but Pogba’s finish had an air of authority about it, as he controlled the ball, feinted and then dispatched his effort past the helpless Milan goalkeeper Gianluigi Donnarumma.
Having not played for nearly six weeks, Pogba could have been forgiven for displaying some ring-rust in a role wide on the left but his simplicity of passing helped United improve and see out their victory.
Man Utd’s future number one?
While Pogba provided the difference at one end of the pitch, United will also leave Italy thankful for Henderson’s form at the other.
The 24-year-old was criticised in the aftermath of the first leg for failing to save Simon Kjaer’s added-time equaliser but he atoned in perfect fashion.
His reflex save to deny Ibrahimovic only told part of the story of a near faultless display.
Henderson has now kept 11 clean sheets in 18 appearances for the club and is making a determined case to be considered ahead of long-time number one David de Gea.
The Spaniard has kept 10 clean sheets in 29 matches this season but aside from just the numbers, Henderson is also impressing with his communication and appears to have gained the confidence of United’s back four. – BBC
