Jesse Lingard heaped praise on Lionel Messi after the Argentine scored two brilliant goals to help Barcelona book a spot in the Champions League semi-finals.
Lingard says Messi "brought his A game" on Tuesday night at the Camp Nou as the five-time Ballon d'Or winner scored a brace in the space of three minutes that killed United's hopes.
Philippe Coutinho added the third on the night, summing a 4-0 aggregate triumph and after the match, United attacker Lingard told BT Sport: "You can't afford to make mistakes in these games.
"We dominated the first 15 or 20 minutes, and it could have been different if we had put our chances away.
"Messi is one of the best players in the world and he brought his A game tonight. All we can do now is move on.
"We were always going to be underdogs, but we had to back ourselves and believe. If the first 15 minutes had gone our way, it would have been a different game.
"Chances in these games are massive and if we take them it's a different game. The Champions League is a big competition and we'll be fighting to get back in."
