A Lionel-Messi inspired Barcelona ended Man Utd's Champions League run at the quarter-final stage as they finished the job in style at the Nou Camp.
Ole Gunnar Solskjaer's side have done well to get as far as the last eight, but after the miracle of Paris in the last round, this tie, in truth, proved a step too far for the Reds.
Trailing 1-0 from the first leg, United started brightly but were then undone by Messi's brilliance and the latest in an increasingly long list of howlers from 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.
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.
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 we 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

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.

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 we are to compete with the European elite.
