Arsenal have finally been beaten in the FA Cup.
The two-time holders of the FA Cup were knocked out on their own home turf, as Watford put in a fine performance at the Emirates Stadium.
After a goalless first half, Odion Ighalo fired the visitors in front when he rolled Gabriel and finished with aplomb.
Adlene Guedioura sent the home fans wild with a top corner golazo soon after.
Danny Welbeck found a late goal for Arsenal to set up a frantic finish, but Welbeck later missed a golden opportunity to level.
