Cristiano Ronaldo's last-gasp heroics, the miracle of 1999, Harry Maguire lifting the roof of Old Trafford & Man Utd's craziest European comebacks - ranked

United were booed off at half-time in their Champions League group stage meeting with Atalanta at Old Trafford, and the fans' frustration was understandable. Ole Gunnar Solskjaer's men had performed horribly during the opening 45 minutes and trailed 2-0 at the break to an impressive Atalanta side, who had opened the scoring through Mario Pasalic before Merih Demiral deservedly doubled their advantage.

However, Marcus Rashford breathed new life into the contest with a fine finish eight minutes into the second half before Harry Maguire drew United level with an emphatic strike.

The stage was, thus, perfectly set for Cristiano Ronaldo to steal the show and the Portuguese duly obliged, heading home an 81st-minute winner to spark wild celebrations in the stands.

"We have a habit of doing this at this club," Solskjaer pointed out in his post-match interview on BT Sport. "The fans are a big part of this club. The singing section there kept the players going with their belief. And that is what you do at Manchester United on a Champions League night."

United were atrocious for the majority of their Champions League group stage clash with Juventus. They were lucky to be only trailing to a solitary strike from Cristiano Ronaldo after 85 minutes of play, and only managed to nick a 2-1 win thanks to a fine free-kick from Juan Mata and Alex Sandro's last-gasp own goal.

Jose Mourinho obviously didn't care about the merits of United's victory, though. His primary concern was sticking it to the Juve fans that had been whistling and booing the former Inter coach throughout the game by cupping his ear to the Turin crowd as he swaggered onto the pitch at full-time.

"In a beautiful Italian city, they insulted me for 90 minutes," an unrepentant Mourinho told BT Sport. "I didn't insult them. I just made a little thing. But I know that the millions of Inter fans are happy with that!"

Unfortunately for Mourinho, it was to be his last truly enjoyable night as United manager, as he was sacked just over a month later after a rotten run of form in the Premier League.

Ten years on from the horror of the Munich air disaster, United had recovered their former swagger and were one tie away from the European Cup final they had long coveted.

They won the first leg of the semi-final at Old Trafford 1-0, but a one-goal advantage counted little at Santiago Bernabeu against six-time winners Real Madrid.

The Spaniards were leading 3-1 at half-time and were not known for giving up big leads at home. But Matt Busby's side had thick skin, and David Sadler made it 3-2 with a close-range finish to put them in charge on away goals.

Their place in the final was then clinched by a goal from Bill Foulkes, a survivor of the Munich crash. A tearful Bobby Charlton said afterwards: "I can't explain how I feel, except that this is a wonderful night for Manchester United."

The Parisians had burst United's bubble at Old Trafford in the first leg of their last-16 Champions League tie, winning 2-0 and inflicting the first defeat on Ole Gunnar Solskjaer after a magical start of 10 wins from his first 11 matches. The defeat was made worse by Paul Pogba being sent off, so no-one gave United a chance at Parc des Princes.

But there's nothing like an early goal to strike fear into opponents, and Romelu Lukaku's second-minute strike did just that. The Belgian then put United back in front after Juan Bernat's equaliser, leaving United one goal from an unlikely victory on away goals.

PSG dominated the second half and should have put the tie beyond doubt, but looked to have done enough as United struggled to get into their area. Yet a hit-and-hope effort from Diogo Dalot changed everything when VAR, which had only just been introduced, spotted a handball from Presnel Kimpembe had blocked his shot.

Marcus Rashford showed nerves of steel to smash home the penalty and complete an incredible comeback that left Rio Ferdinand demanding that Solskjaer be given the United job on a full-time basis.

"Listen, Man Utd might not thank me but get the contract out, put it on the table," the retired centre-back infamously stated. "Let him sign it, let him write whatever numbers he wants to put on there, given what he's done since he's come in. Ole's at the wheel, man. He's doing it."

Later in the month, Solskjaer signed a three-year deal to continue as manager...

There were people streaming out of the exits at Old Trafford after United fell 4-2 down on the night, and 6-4 down on aggregate. One could somewhat understand why. They had watched the worst Manchester United team in Premier League history throw away a two-goal lead in normal time and then fail miserably to deal with Lyon's 10 men in extra time.

However, those deserters really should have known better. As Amorim said of the mysterious power of Old Trafford on a European night, "Here, it is never over. Here, everything is possible."

He was right, too. After Bruno Fernandes pulled a goal back from the penalty spot, Kobbie Mainoo curled home an equaliser in the 120th minute of a crazy quarter-final second leg. Penalties appeared inevitable but United weren't done yet, as Amorim's old-school tactic of sticking a centre-half up top paid off spectacularly, with Harry Maguire heading home an injury-time winner to send Old Trafford into ecstasy.

"The sound of the stadium was the best ever," Maguire told TNT Sports. "Some people collect shirts, scarves, but I want to keep that sound, it's the best sound in the world.

"I feel for the people who had to leave at 4-2 because of the traffic, they will be gutted!"

Juventus were United's great rivals on the European stage during the mid-to-late 1990s and were gunning for their fourth consecutive Champions League final.

United had salvaged a 1-1 draw in the first leg at Old Trafford with a last-gasp Ryan Giggs goal, but things got off to a nightmare start in the return fixture when Filippo Inzaghi scored twice in the opening 11 minutes. United weren't about to roll over, though, and Roy Keane dragged them back into contention before Dwight Yorke equalised with another header before half-time.

Keane and Scholes, meanwhile, picked up yellow cards that ruled them out of the final, but they played on as if their lives depended on United winning - which is exactly what they did.

Andy Cole sealed a famous win by squeezing the ball inside the near post late on, rounding off what many regard as the club's greatest European away performance - and one which will forever be associated with their iconic captain Keane.

"Pounding every blade of grass, competing as if would rather die of exhaustion than lose, he inspired all around him," Sir Alex Ferguson later wrote of the Irishman. "I felt as if it were an honour to be associated with this player.”

It remains the greatest night in Manchester United's modern history, an unforgettable ending to an unforgettable season. And just like so many occasions in that enthralling campaign, Sir Alex Ferguson's side did it the hard way in the Champions League final at Camp Nou.

The defence bungled the wall from Mario Basler's free-kick and, in their biggest game in 33 years, United were a goal down after six minutes. They could have conceded more in the second half, with Peter Schmeichel making two huge saves, and both Mehmet Scholl and Carsten Jancker hitting the woodwork.

But United stayed in the game and when they won a 90th-minute corner commentator Clive Tyldesley uttered those immortal words: "Can Manchester United score? They always score."

After the ball was knocked around the box, Teddy Sheringham turned it in to equalise. Extra-time beckoned, but United didn't need it. Less than a minute after levelling, Sheringham nodded David Beckham's corner to the back post, where Solskjaer prodded it in.

The goal completed the most dramatic of escape acts and saw United become the first English team to win the treble.

"I can't believe it, I can't believe it," a visibly stunned Ferguson said. "Football, bloody hell!"
