Indeed, Cazorla was brought on in the 74th minute and provided the assist for Aaron Ramsey's 83rd-minute equaliser. That got Arsene Wenger's side on the comeback trail and Olivier Giroud finished the job in the 90th minute, as Arsenal salvaged a 2-2 draw at Goodison Park having been 2-0 down.
As for Bellerin, the full-back didn't get to make an appearance but has been a regular on Arsenal's bench this season, quite a feat for a player who was only part of their NextGen side a couple of seasons ago. In pre-season, Bellerin sprinted so quickly that he officially beat Theo Walcott's speed record to become the north London's side fastest ever player.
A promising campaign, then, could be in store for the 19-year-old, who thoroughly impressed during pre-season, especially in the Emirates Cup.
Next up for the Gunners are Besiktas for the second leg of their Champions League play-off.
Arsenal have four points to their name in the Premier League after their 2-2 draw with Everton, having beaten Crystal Palace at the Emirates Stadium in their season opener.
