Defender Nacho Monreal has warned his team-mates they must win all their remaining games if they are to be satisfied with their campaign.
Back in his natural full-back position, the 29-year-old showed great composure to score Arsenal's first goal at Old Trafford on Monday night.
It was the Spaniard's first goal of the season and he was clearly delighted to be on the scoresheet at the end of the game.
"I'm very happy to play and secondly because I could score and help the team win," the defender told the club's official website.
"I am a player who doesn't score too many goals so when I do I'm very happy.
"I didn't have time to think because David de Gea came out very quickly. I controlled it well and I saw the space and tried to put the ball there.
"I'm very happy because I finished the goal.
"We are now on the way to repeat that and we want to win the FA Cup again. We have the semi-final at Wembley which is a great stadium, so we are very happy with the victory.
"We have to keep going in the same dynamic and we only have 10 games left before we finish the season.
"We are playing in three different competitions and we want to win all of them. We have to keep going."
