Arsenal fell behind just 56 seconds into Saturday's Premier League home game against Fulham.
The early goal was the product of two mistakes - firstly by Bukayo Saka and then Gunners keeper Aaron Ramsdale.
Saka played a poor pass from near the halfway line that was intended for Ben White but went nowhere near the defender. Instead, the ball rolled into the path of Fulham midfielder Andreas Pereira.
With Ramsdale frantically running backwards, Pereira tried his luck with a hopeful shot from almost 30 yards.
Pereira's effort lacked power but it caught out Ramsdale, who struggled to change direction and was beaten low to his right.
Arsenal recently signed Brentford keeper David Raya on an initial loan deal to provide competition for Ramsdale.
It may not be long before Raya replaces Ramsdale as Arsenal's first-choice stopper.
