Carry the giddy smile all week, Arsenal fans. Keep it going because football is fickle. The Gunners won the corresponding North London Derby match by the same scoreline last season and will have largely forgotten about it now.
This feels different in more ways than one, though. After a derby day win, and a brilliant one at that, enjoying the moment itself rather than what it may or may not signify in terms of progression, a title challenge or being light-years further on than Tottenham is important, and it's what the players will be doing.
They had their day, earnt it during the glory of an early kick-off, and will have celebrated accordingly. Their warning came just over 24-hours later, though. The gap between Arsenal and Manchester City remained as Pep Guardiola's side dismantled Manchester United - the same side that are the only team to have stopped Mikel Arteta from winning this season - but the effect of the win felt different.
