Danny Welbeck sinks Manchester United as Arsenal reach FA Cup semifinals

Discarded striker Danny Welbeck returned to haunt Manchester United by scoring the winning goal as Arsenal reached the FA Cup semi-finals with an enthralling 2-1 victory at Old Trafford on Monday.

England international Welbeck, who joined the Londoners last summer after his United career stalled, pounced on a horrendous back pass by Antonio Valencia in the 61st minute to send the holders through.

In a rip-roaring first half Nacho Monreal's cool finish put Arsenal ahead in the 25th minute but Wayne Rooney's diving header evened it up four minutes later.

United, who will now ponder a second consecutive season without silverware, ended the match with 10 men after Angel Di Maria was red-carded for grabbing the referee's shirt just seconds after being booked for diving.
