#3 Arsenal's newfound character
Tottenham have had a good record in the past few seasons when these two sides meet, and most of the footballing world (including me) thought that they would come away from the Emirates with the result tonight.
Though it seems like the Gunners' fortunes are being turned around, and there could soon be another power shift in North London, as Arsenal look to be Arsenal again instead of looking like a shell of their former selves.
Aside from Emery, another man crucial to this shift is summer signing Lucas Torreira, who is going leaps and bounds every game, establishing himself as a firm favourite amongst the Arsenal supporters.
Under Wenger, this game would likely have been over at halftime, and Tottenham would have hounded Arsenal in the second half and gone home with 3 points and the bragging rights, but all that seems to be in the past now, as the Spaniard seems to have ushered in a bright new era at the Emirates.
