For a long while this season, Arsenal have looked an unstoppable force.
They arrived at Sunderland on Saturday looking to extend their winning run to 11 consecutive games and keep a club-record ninth clean sheet in a row.
Victory would have sent them eight points clear at the top by the end of the day, but the Black Cats that crossed the Gunners' path at the Stadium of Light were set on being disruptive.
Regis le Bris' side, the pre-season relegation favourites, have surpassed all expectations on their return to the Premier League and are sitting pretty in the European places for now.
