Arsenal are enduring one of their worst seasons since Arsene Wenger took the reins of the club in 1996 and it is showing little sign of improvement after they were denied yet another clean sheet.
Petr Cech saw his net breached just seven minutes into their Premier League clash against Brighton on Sunday as Lewis Dunk scored after being teed up by his defensive partner Shane Duffy.
The concession means that they are now 11 games without a clean sheet in the division this season, which is their longest run without shutting the opposition out since February 2002.
