Danny Welbeck's winner against his old club sealed Arsenal's path to Wembley with a 2-1 victory at Old Trafford.

And despite being criticised for dressing-room celebrations by the likes of Liverpool legend Jamie Carragher and United great Paul Scholes, the Gunners were quick to get the selfies going.

Sanchez also congratulated goalscorer Welbeck by uploading a snap of him celebrating with the caption: "We march on this one is for you haters out there. Goodnight."

Nacho Monreal opened the scoring with a rare goal before Wayne Rooney's equaliser and he got in on the social media act too.
