Arsenal are through to the 2014/15 FA Cup semi-finals after getting the better of Manchester United on Monday night.
Danny Welbeck returned to his former club for the first time since joining the Gunners in the summer to deliver the killer blow in the 61st minute of the quarter-final as the north Londoners won 2-1 at Old Trafford.
Arsene Wenger's side opened the scoring in the 25th minute when Nacho Monreal got on the end of a pass from Alex Oxlade-Chamberlain to beat David De Gea, tallying just his second goal for the club.
However, United were level four minutes later when captain Wayne Rooney nodded home Angel Di Maria's cross from eight yards out.
Midway through the second half it was Arsenal who edged in front through Welbeck, who was discarded by Louis van Gaal upon his arrival at United.
The England striker pounced on a poor backpass from Antonio Valencia to round De Gea and slot home prior to a raucous celebration.
That preceded Di Maria's mindless red card which came after he was cautioned for diving before pulling on the shirt of referee Michael Oliver in protest at the initial decision.
The extra man gave Arsenal the ascendency to hold onto their advantage and secure their first win at Old Trafford in 11 visits to be just a couple of steps away from defending their FA Cup crown.
