After losing their first two games of the season against Manchester City and Chelsea, the Gunners are moving in the right direction under new head coach Unai Emery.
Sokratis Papastathopoulos was one of the key players who could impress but he could be facing a spell on the sidelines after coming off injured in the first-half against the Toffees.
After his central defensive partner Shkodran Mustafi lost the ball in a dangerous area, Sokratis was forced to bring down Theo Walcott which earned him a yellow card and minutes later he limped off.
Following that incident, a number of Arsenal supporters spotted how the Greece international reacted to Mustafi.
