Sunderland earned a point against Premier League leaders Arsenal on Saturday with a dramatic late equaliser.
But while Brian Brobbey's acrobatic 94th-minute strike took the headlines and Gunners boss Mikel Arteta talked of the "chaos" caused by Sunderland's direct approach, one of the hosts' more unusual tactics also caught the eye.
The Black Cats attempted to limit Arsenal's threat from set-pieces - specifically long throw-ins - by moving the advertising hoardings to give the Gunners less room for their run-ups.
"It might have been the wind," Sunderland boss Regis Le Bris joked after the game.
