Arsenal defender Nacho Monreal has expressed his satisfaction at having scored the opening goal for the Gunners in their 2-1 win over Manchester United at Old Trafford.

It was a beautifully worked goal by Arsenal, starting with Mesut Ozil, who passed the ball onto Alex Oxlade-Chamberlain for him to waltz into the United penalty box and open the goal up for Monreal to slot it past an onrushing David de Gea.

It was the Spaniard's first goal this season and his second for the Gunners since March 2013. The Gunners failed to hold on to the lead with Wayne Rooney equalising for the Red Devils within four minutes of Monreal's goal.

However, it was Danny Welbeck's goal which did the trick for the Gunners, as the England international latching on to a mistake from Antonio Valencia, securing Arsenal's first win at Old Trafford in almost a decade.

The win has taken Arsenal to their second FA Cup semi-final in as many years where they will face either Bradford or Reading in their bid to retain the Cup.

"I'm very happy to play and secondly because I could score and help the team win. I am a player who doesn't score too many goals so when I do I'm very happy," Monreal told Arsenal's official website.

"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," he added.
