Messi has 45 goals in just 42 appearances in all competitions for Barcelona this season

Manchester United's Champions League run ended in the quarter-finals as Lionel Messi inspired Barcelona to a crushing victory in the second leg at the Nou Camp.

United, trailing 1-0 from the first leg, started brightly but were then undone by brilliance from Messi and a glaring mistake from goalkeeper David de Gea.

Messi put the hosts ahead with a fine curling effort from 20 yards in the 16th minute and four minutes later De Gea let a weaker shot from the edge of the area squirm under his body for the Argentine's second.

Philippe Coutinho added a third for Barca in the 61st minute, curling a stunning effort into the top corner from distance.

United hit the bar inside the first 40 seconds through Marcus Rashford but were dominated after going behind.

Alexis Sanchez's diving header, which was spectacularly saved by Barca goalkeeper Marc Andre ter Stegen in the 90th minute, was as close as the visitors came in the second half.

It was a sobering night for United manager Ole Gunnar Solskjaer on the ground where he scored his most famous goal, the stoppage-time winner in the 1999 Champions League final.

Barca now meet either Liverpool or Porto in the semi-final, with the Reds taking a 2-0 lead into Wednesday's second leg.

Mistakes costly but United outclassed

United were playing in the quarter-finals for the first time since 2014

United were always facing a difficult task as they attempted to overturn a first-leg deficit for the second round in a row.

Just like in the last 16, when they stunned Paris St-Germain at the Parc de Princes, United started the game fast, looked dangerous on the counter-attack and had opportunities - a poor touch from Scott McTominay in the area saw a chance wasted shortly after Rashford's first-minute effort.

That start raised hope of an improbable comeback but Barcelona soon took charge and were awarded a penalty in the 11th minute for Fred's clumsy challenge on Ivan Rakitic in the area only for the decision to overturned after the referee consulted VAR.

United survived that scare but their hopes were effectively ended when they allowed Messi to score twice in four first-half minutes.

The Argentine dazzled for his first goal with a nutmeg of United midfielder Fred and a perfect finish into the bottom corner, but Ashley Young gave the ball away in the left-back position and the visitors' defence backed off rather than attempt to stop the shot.

Then De Gea, so often United's star player, made a huge mistake by allowing Messi's tame shot from 20 yards to slip under his body and in.

Unlike in the first leg, Barcelona looked as though they could could cut their opponents open at will.

Messi was at the centre of that attacking threat with Jordi Alba also marauding forward from left-back and the Barcelona midfield outplaying their United counterparts, both in terms of their control of the ball and pressing to win it back.

No United player made any real impact on a match that proved how great a rebuild is required under Solskjaer if they are to compete with the European elite.

It's Messi again for Barcelona

Messi has scored 24 Champions League goals against English clubs

After a quiet first leg it was no surprise to see Messi take control in the second.

The 31-year-old often stood still in the United half but would burst into life with devastating effect.

Messi's double took his goals tally to 45 in 42 games this term and made him the outright top scorer in this season's Champions League.

It was yet more success for the Argentine at United's expense, having also scored against them in both the 2009 and 2011 Champions League finals.

The home fans chanted Messi's name again and again during the game, but his performance was not just about his goals.

He amazed the jubilant fans in first-half stoppage time when turning Phil Jones on the halfway line, driving towards the area, and beating Jones twice more before feeding Alba down the left. Alba then crossed for Sergi Roberto but De Gea blocked the Spaniard's close-range shot on the goal line.

In such sublime form, Messi looks intent on leading his side to a first Champions League title since 2015.

And the celebratory mood at the Nou Camp was summed up in the second half when the Barcelona supporters loudly cheered news of Ajax's winning goal against Cristiano Ronaldo's Juventus in the night's other quarter-final second leg.

Man of the match - Lionel Messi (Barcelona)

A number of Barcelona players impressed - Jordi Alba, Philippe Coutinho and Sergio Busquets - but Lionel Messi was unquestionably man of the match

'They were a couple of levels above' - manager reaction

Manchester United boss Ole Gunnar Solskjaer on BT Sport: "I have to say Lionel Messi is top quality and he was the difference of course. At 2-0 it was game over.

"He's different class. He and [Juventus forward] Cristiano Ronaldo are the best players of the last decade, everyone agrees on that one. Messi showed his quality.

"We have to aspire to get to that level of Barcelona. We can get there but we have loads of work to do. If we want to get back to Manchester United's true level, true traditions, we have to challenge Barcelona.

"They were a couple of levels above over the two games."

United's heaviest defeat - the best stats

Barcelona have qualified for the Champions League semi-finals for the first time since the 2014-15 campaign.

Manchester United have been eliminated at the Champions League quarter-final stage on seven occasions - more than any other side.

Barcelona's Lionel Messi scored his first Champions League quarter-final goals since April 2013 versus PSG, ending a run of 12 matches and 50 shots without a goal in quarter-final matches.

This was United's heaviest aggregate defeat (4-0) in a two-legged European tie. Their previous heaviest was 5-2 by AC Milan in the 1957-58 European Cup semi-finals and 4-1 v Atletico Madrid in the last 16 of the 1991-92 Cup Winners' Cup.

Manchester United have lost four consecutive away matches for the first time since October 1999.

Messi has scored 45 goals for Barcelona this season - 10 more than any other player in the top five European leagues (England, France, Germany, Italy and Spain).

Messi has scored twice as many Champions League goals against English sides as any other player (24 goals).

United lost five Champions League matches this season, their joint-most in a season (also five in 1996-97).

Spanish teams have lost just one of their past 24 Champions League knockout matches against English sides, winning 16. Leicester City's 2-0 win over Sevilla in March 2017 was the only victory for an English team in that time.
