Wenger sent off as Arsenal lose at Old Trafford
Manchester United came from behind to defeat Arsenal 2-1 at Old Trafford after the visitors had made all the running. Arsenal looked on course for a fifth successive victory after they dominated the first period and took a deserved lead just before the break through Andrey Arshavin.
But two home goals in the space of five second half minutes turned the game in The Reds favour.
The reason for the Frenchman's ire was seeing Robin van Persie's injury-time leveller ruled out for offside.
