It's fair to say Arsenal were far from their comfort zone when they played Sutton United in the FA Cup on Monday night.
The cramped dressing rooms, the plastic pitch and, according to this clip that went viral on Twitter, the rather unorthodox defensive tactics of the Sutton players.
The television cameras captured the bizarre moment when, as Arsenal speedster Alex Oxlade-Chamberlain steamed past him down the wing, Sutton captain Jamie Collins tried to put him off with what onlookers described as a 'headbutt'.
There was no stopping Oxlade-Chamberlain, but Collins perhaps hoped he'd be distracted if he got as close as possible without making contact.
