RANKED: Man Utd’s greatest European away nights, from Juventus and Bayern Munich comebacks to Marcus Rashford's penalty in Paris

A Dwight Yorke double had given United a 2-0 win in the first leg of this quarter-final tie, but this was the golden age of Italian football and San Siro one of its most intimidating arenas.

And Inter had a weapon they had not had at their disposal at Old Trafford: Ronaldo Nazario.

The Nerazzurri gave United numerous frights before Nicola Ventola put them ahead in the second half, while both Henning Berg and Peter Schmeichel played their part in keeping Inter at bay. They were, though, hugely fortunate to see Ze Elias drag a shot wide of the post which would have levelled the tie.

United kept their nerve, and down the other end a cushioned header from Andy Cole teed up Paul Scholes to side-foot past Gianluca Pagliuca and score an away goal that effectively ended the tie.

London might not have been top of many United fans' ideal European away destinations, but their semi-final second-leg romp against Arsenal was a night to savour.

United held a slender 1-0 advantage from the first leg and the Emirates Stadium, for once, was a cauldron of noise at kick off.

The Red Devils' weathered an early storm before Park Ji-sung pounced on a Kieran Gibbs slip to silence the Arsenal fans after only eight minutes.

Moments later, Cristiano Ronaldo netted a stunning free-kick to effectively end the tie, and in the second half the Portuguese further twisted the knife into the Gunners' hearts by starting and finishing a lightning-quick counter-attack.

The only negative was Darren Fletcher's red card, meaning he missed the final against Barcelona.

United must have been thanking their lucky stars when they avoided Real Madrid and Barcelona in the semi-final draw, facing surprise package Schalke instead.

The Red Devils' utterly dominated the Germans on their own turf, and it was only thanks to a series of saves from a young Manuel Neuer that the scoreline was kept dignified.

Ryan Giggs finally found a way past the goalkeeper midway through the second half, before Wayne Rooney made it 2-0, burying the ghosts of Gelsenkirchen, where he had been sent off for England against Portugal in the 2006 World Cup.

The two sides were clearly woefully mismatched, something Ferguson appeared to underline by fielding practically a second-string side for the return leg at Old Trafford, which his side still won 4-1 to complete a crushing 6-1 scoreline on aggregate.

George Best was still a teenager when he visited the Estadio da Luz, but he left it a man after making a name for himself with a sensational performance against Eusebio's Benfica.

United were defending a 3-2 lead from the first leg, and in the reverse fixture, the boy from Belfast opened the scoring with a header.

He then demonstrated his pace and skill with a dash through the middle past two defenders before arrowing the ball into the net.

John Connelly, Pat Crerand and Bobby Charlton completed the rout, with the only goal Benfica managed an own goal from United's Shay Brennan.

Busby's side ended up losing in the semi-finals to Partizan Belgrade, but they had already sounded a warning to the rest of Europe, and two years later they would be back, beating Benfica in the 1968 European Cup final at Wembley.

And as in Lisbon, Best was in the thick of the action.

United played Roma six times in the space of a year, leading to a huge rivalry developing between the teams, as well as their fans following shocking scenes at the previous year's fixture when riot police had beaten visiting supporters.

On their third trip to the Italian capital for the 2008 quarter-finals, it was United who administered the beating on the pitch.

They controlled the game from the first minute to the last, and went ahead with one of Ronaldo's best-ever goals, making a lung-busting run into the area and leaping high into the air to head Scholes' cross into the net.

"It's the most miraculous goal that I've ever seen," Gary Neville later remarked. "He jumped from the edge of the box and headed it on the penalty spot at full speed. And he'd sprinted from the halfway line nearly."

Rooney sealed the victory in the second half, giving United an ideal foundation for the second leg, where Carlos Tevez clinched a 1-0 win for a resounding 3-0 aggregate score.

United had just pipped Chelsea to the Premier League title, but their paths crossed again soon after, only this time it was 2,000 miles away in Moscow.

Ronaldo, who had just finished the season on 41 goals, inevitably gave United the lead with a towering header, and the Red Devils should have added to their lead in a dominant first half, with Michael Carrick and Tevez both going close.

But Frank Lampard levelled on a break and the momentum shifted to Chelsea in the second half. Didier Drogba was sent off in extra-time for raising his hands, but the game had to be decided on penalties.

Remarkably, Ronaldo missed his, leaving John Terry to clinch the holy grail for Chelsea.

Instead, the captain slipped on the wet pitch and his shot hit the post.

United continued to convert their penalties until Edwin van der Sar saved from Nicolas Anelka, giving Sir Alex Ferguson his second Champions 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.

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, and 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 the most unlikely of comebacks. Later in the month, Solskjaer signed a three-year, permanent contract as United manager.

It was the best day 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 the Camp Nou.

The defence bungled the wall from Mario Basler's free-kick and, on their biggest night in 33 years, United were a goal down after six minutes.

They could have conceded more in the second half, with Schmeichel making two huge saves and 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, and less than a minute later 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.

Juventus were United's great rivals on the European stage 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 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 headed United back into contention before Dwight Yorke equalised before half-time with a diving header.

The game had everything: Jaap Stam headed the ball off the line, Schmeichel made two point-blank saves from Inzaghi, who then had a goal ruled offside.

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.

United were heading through on away goals regardless, but Andy Cole made sure of victory by squeezing the ball inside the near post late on, rounding off what many regard as the team's greatest European away performance.
