Top five: Reasons behind Arsenal's transformation
Find out why Arsenal have dramatically improved recently
After Arsenal were beaten 3-1 by Aston Villa on the opening day of the season, nobody would have predicted that they would win their next 10 matches in all competitions.
But, remarkably, that's precisely what the Gunners have managed to do.
On Tuesday night, Arsene Wenger's men celebrated their 10th straight win with a comfortable 2-0 win over Napoli in the Champions League group stages.
Just where did it all start going so right?
1. Mesut Ozil's arrival
Who would have thought it, eh? Adding a world-class star to your ranks will, in fact, make your squad significantly stronger.
After years of living with their means, Arsenal finally splashed the big cash this summer on Real Madrid's classy playmaker Mesut Ozil.
The Germany international has already settled in at Arsenal with impressive ease, with one goal and multiple assists to his name already.
An inspired signing who could soon cement his status as the Premier League's best player.
2. Improvement of Ramsey and Giroud
Most Arsenal fans would have happily driven Aaron Ramsey to the airport if a half-decent offer had come in for the Welshman last season, but the Welsh midfielder has been the Gunners' best player this season.
Just behind him in the performance charts is Olivier Giroud who, like Ramsey, has been outstanding so far this term.
They've both improved so much that they currently feel like brand spanking new signings.
3. Positive atmosphere inside Emirates Stadium
Boos and jeers have been the most common sounds at the Emirates Stadium in recent season, as the supporters became increasingly frustrated with inconsistency and that humiliating trophy-drought hanging over the club.
The trophy-drought hasn't gone yet, but the Arsenal fans sense that could all change this season following this morale-boosting hot streak.
Rather than a tense and nervy atmosphere, the Arsenal players are currently performing in a much more positive environment, and it's helping them no end.
4. Tight-knit squad
Arsenal have a small squad - perhaps a little too small - but they're a tight-knit bunch without a disruptive influence at the club.
Familiarity can breed success, and the players all appear to be on a similar wavelength. This allows newcomers, particularly those of Ozil's quality, to settle without any major hassle.
Wenger always said he had confidence in this ground of players - and now we can understand why.
5. Arsene Wenger's experience
Shame on all of those Arsenal supporters who wanted Wenger to leave the club at some point within the last 24 months.
The Frenchman is one of the Premier League's best coaches and a rare type of manager who can remain calm when those around him are losing their heads and splashing silly money on players who simply aren't worth it.
Wenger was under intense pressure to make a big signing in the summer, but remained patient and pulled off the best coup of this - or any other - transfer window with the signing of Ozil.
Wenger knows best. Those words are now ringing truer than ever before.
