Manchester United forward Wayne Rooney has highlighted the importance of bouncing back quickly from the defeat to Arsenal on MUTV.
Arsenal took the lead in the quarter-final tie through Nacho Monreal, who fired the ball home past goalkeeper David de Gea from close range.
Rooney himself restored parity just before the half-hour mark when he headed home from an Angel di Maria cross.
However, Arsene Wenger’s side had the last laugh on the night.
Former United striker Danny Welbeck scored what proved to be the winner just past the hour mark on his return to Old Trafford for the first time since leaving the Manchester outfit in the summer of 2014.
The defeat has ended all realistic chances of United winning any major trophies this season, and Rooney has now insisted that the players need to pick themselves up soon.
"After getting the equaliser we felt we created enough chances to go on and win the game, but it wasn't to be,” the 29-year-old England international told MUTV.
"We knew we had a great opportunity to go on and win the FA Cup if we won this game, so we're extremely disappointed.
"We've got a tough few games coming up. We have to move on and make sure we're right for the game on Sunday.”
United did put up a good fight against Arsenal, but in the end they fell short and deservedly lost the quarter-final tie.
Louis van Gaal’s side had 58% of the possession, 10 shots of which five were on target, and three corners.
Visiting Arsenal had 42% of the possession, 11 shots of which eight were on target, and three corners.
Next up for United is a Premier League clash against Tottenham Hotspur on Sunday. The Manchester outfit will be at home for that match, and they will need to step up their game and pick up the three points.
Just like Arsenal, their North London rivals Tottenham are also in the running for a top-four finish in the Premier League this season.
After facing Spurs, United will confront Liverpool, who are aiming for a Champions League place as well.
Psychologically, defeat to Arsenal on Monday is a huge blow to United, but Van Gaal and his players cannot afford to dwell on it for too long.
