Club Brugge defender Simon Deli gift-wrapped Manchester United's passage into the Europa League round-of-16 after a moment of absolute madness at Old Trafford.
United strolled into the next phase of the knockout stage courtesy of a 5-0 rout in the second leg that made it 6-1 on aggregate.
‘HORRENDOUS’: Controversial VAR calls rock Premier League clash
The ease of United's victory owed in large parts to an inexplicable first half red card to Deli, when the tie was delicately poised at 0-0.
The Brugge defender decided to take matters into his own hands - quite literally - when Daniel James shot from the edge of the penalty area.
Goalkeeper Simon Mignolet appeared to have the shot covered but to the astonishment of viewers, Deli decided to throw a hand out to save it himself.
Incredibly, the defender wasn't sent off straight away, with VAR eventually coming to the conclusion that the deliberate handball warranted a straight red card.
United's new signing Bruno Fernandes tucked away the penalty to make it 1-0 on the night and the rest was history as the home side used their numerical advantage to brutal effect.
Not surprisingly, the inconceivable red card for Deli dominated discussion on social media, with fans calling it one of the stupidest incidents they've seen in some time.
A Brugge player has just been sent off for the most ridiculous handball I’ve ever seen.— Ciarán (@BackPostHeader) February 27, 2020
The defender from Brugge who did the Handball Superman save basically ended the night for his team. It's as if he wanted to get an early start on Manchester nightlife.— Mikel and Dime (@succa99) February 27, 2020
Is that Brugge defender throwing the match? That’s an incredibly foolish handball to commit. Easy red card.— Raphielle Johnson (@raphiellej) February 27, 2020
This club Brugge defender should be punished by the club. What nonsense handball is this?— Fire & Ice (@fidvictor) February 27, 2020
Stupid handball that. Brugge looked good with the ball. I'm happy as a utd fan but so so so stupid regardless— FPL Flooded (@FPL_Flooded) February 27, 2020
The Brugge defender has made a world class save. Deliberate handball. Its always a red card. How it needed to be checked for anything else is ridiculous #MUNBRU— Tom O'Donoghue (@TNODonoghue) February 27, 2020
Haha that handball is brilliant from the Brugge defender 😂😂 What was he doing?! The keeper was right behind him 😂😂— Jon Bell (@jonbell84) February 27, 2020
That is the most blatent and stupidest handball I’ve seen in a long time, but then again if I knew Mignolet was in goal behind me I’d probably do the same. #MUFC— Matth (@Matthewj7) February 27, 2020
Odion Ighalo celebrated his first start for Manchester United with his maiden goal for the club after Fernandes' 27th-minute penalty.
Ighalo scored United's second goal in a 5-0 Europa League second-leg round-of-32 win over 10-man Club Brugge at Old Trafford on Thursday.
‘Big dream’ for United signing comes true
The 30-year-old Nigeria striker celebrated by lifting up his United shirt to reveal a t-shirt which paid tribute to his sister Mary, who died in December.
Ighalo had taken a pay cut to secure a shock deadline-day loan move to United from Chinese Super League club Shanghai Shenhua.
He told BT Sport: "It's a big dream for me, yes. A great moment.
"I have been waiting for this, played three games, though I didn't play much and no goals.
"There has been a little bit of pressure, but now I got a goal to start my Manchester United goal career and it is a team I have supported since I was young, so it is very good.
"I am very happy and I am grateful to God."
Ighalo netted with a close-range finish from Juan Mata's cutback after Bruno Fernandes had scored from the penalty spot.
Scott McTominay gave United a 3-0 half-time lead before midfield colleague Fred put a gloss on the result with two late goals.
Ighalo added: "The confidence was high and we spoke about that before the start. We pushed from the first minute and went all out playing our style.
"The red card was difficult for them with us attacking, and we worked hard until the last minute."
United manager Ole Gunnar Solskjaer praised Ighalo's penalty-box prowess post-game.
"He does exactly what it says on the tin," he said. "He plays up front, he can play with his back to goal and the goal was a good example of what you want of him. He can hold up the ball and he is what we have been lacking a little bit.
"If we hadn't had Odion tonight then Mason Greenwood would have had to play and we have a game on Sunday and that would put us in a tired position. We knew what we got when we signed him."
United are now unbeaten in seven games in all competitions and Solskjaer believes Ighalo and fellow new boy Fernandes have helped boost confidence in the dressing room.
He added: "Today we played attacking football and players combined well. The players had a swagger, confidence and a smile on their faces. The new lads have brought that."
