Arsenal fans have had a few false dawns - days when we thought we had 'our' Arsenal back.
Although Sunday's win over Tottenham may be another of those days, it could also mean that we can sustain it.
For starters, we certainly had the fans back. It was a great atmosphere at Emirates Stadium. Gunners fans played an important part in this performance. It would have been a great experience to be there and taste it.
Arsenal 3-1: Arsenal is 'not far away' from perfect in the first-half, says Mikel Arteta
Mikel Arteta felt it was a very important day, as he hasn't had many such moments in his time as Arsenal manager.
Arteta managed eight home games with crowds before Covid led to ground closures. This was Arteta's fourth north London derby as manager. It was also his first time with Arsenal supporters. Arteta has managed 43 home games and only 12 have been at full stadiums.
He needs days like Sunday to cement his place in the hearts of the fans who were singing his name at every whistle.
It was significant because it brought everyone back together, as fans have been divided over the past few years, including his future.
"The right system with the right team"
Arteta has experienced some tough moments over the last few months. The pressure was building when his team started the season with three consecutive defeats without scoring.
I believe he took the opportunity to examine himself and his methods during the September international break to find a team that he trusts.
He has made many changes to the team's personnel since then. He brought back Gabriel at the centre-half for defence and also made Ben White, his summer signing, available to play with him.
Takehiro Tomiyasu (right-back) and Aaron Ramsdale (first choice in goal) are two other new players.
It's been a relief to have Thomas Partey back after an injury in midfield. He kept Pierre-Emerick Aubameyang as the attack leader, but he also tweaked the system by putting Bukayo Saka on right wing and taking Nicolas Pepe out.
All of them were very good decisions. It seems like the manager is on the pulse of what his best system and best personnel are.
"Collectively, the Team Looks Farmed"
Arteta's approach could have been too complex, but he simplified it and players responded.
After four consecutive wins in all competitions the club's mood is completely different than it was just weeks ago. It is now time to continue this trend.
Next weekend, they will be playing Brighton away. If they beat Crystal Palace on Monday, the Seagulls will be at the top of their league. Arsenal must not let this run stop.
This is a brand new team and a young one. We don't know what the future holds, but I love what I see in these players and how they play together.
After beating Tottenham on Sunday, Arsenal moved ahead of Tottenham. After losing their first three league matches without scoring, and conceding nine goals, the Gunners have now won their next three. They scored five and conceded one goal in their wins.
It was amazing to see how they took control of the game from the beginning. Although there were a lot of Arsenal players who hadn't played in a north London derby, I was struck by how hungry they looked together.
They showed a desire to win the game and really take on Tottenham. It was probably the best first half we've seen from Arteta’s Arsenal.
They've had spells in other games where they were very good before, but not as strong as this one - on such a large occasion.
Because they have a dream to play and score in these games, I'm always happy to see them in the first team.
Saka and Emile Smith Rowe, two of our brightest young talent, did more than that.
Arteta should be credited for this, as he used them in the correct positions on the left and right wings. This was only one example of the way he made the most of his team for this game.
Arsenal still has a lot of work ahead of them. They are rebuilding their image at the moment. But, days like these could be important in that process.
