Arsenal conceded from an indirect free-kick despite putting all 11 players on the goal line during their pre-season victory over Western Sydney Wanderers.
A series of errors initially led to WSW hitting the bar. Further calamity ensued when Aaron Ramsey passed the ball to Emiliano Martinez who then picked it up.
The hosts were awarded an indirect free-kick bang on the six-yard line. In a bid to defend the set-piece, Arsenal decided stick their entire team on the goal line.
The shot from the resulting free-kick was blocked by Nacho Monreal. But unfortunately for Arsenal, Steve Lustica didn’t waste his second attempt. The Australian smashed the ball into the roof of the net.
Arsene Wenger’s side comfortably saw the game out and claimed a 3-1 victory to carry on their good pre-season form.
Olivier Giroud, Ramsey and Mohamed Elneny were all on target for the Gunners.
Arsenal now travel to Shanghai where they take on Bayern Munich on July 19.
