There's little doubt why Arsenal have become many people's preferred choice to claim the Premier League this season.
Consider their results against Fulham and Crystal Palace compared to those identical matches in the previous campaign.
The Gunners have beaten all of them in the current season, but dropped 10 points across those games as they faded in the title race last season.
Impenetrable Rearguard
Arsenal's defensive strength is a primary factor why they are appearing strong to finally fulfil their title target.
They lead the league for clean sheets (6), shots let in (3), attempts against (72), shots on target faced (19) and expected goals against (5.3).
The central defensive pairing of Gabriel and William Saliba is potentially the strongest in the league, with Arsenal maintaining a clean sheet in six of their first nine games.
Set-Piece Proficiency
Their threat from set-pieces is well known, but rival sides still struggle to stop the Gunners from these chances.
They have registered 11 times from set-pieces in the league, a couple extra than any other side, with 69% of their goals coming from these situations.
"Arsenal can do a bit of everything now. The whole team has a fear factor. People are just wary of them and it is great to see."
Title Potential
What is even more remarkable about Arsenal's commencement to the campaign is they have also encountered Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City at home - and are still ahead by four points at the top.
While they continue triumphing, their historic competitors face difficulties. This marks the initial occasion at this point of the season since 1992 that none of Manchester City and United, Liverpool or Chelsea are in the Premier League top four.
The expectations was on boss Mikel Arteta at the beginning, having allocated around £250m on eight summer acquisitions in search of that elusive first title since 2004.
But the spending has so far yielded results in remarkable manner, with his side second top scorers in the league and possessing the tightest defense, despite numerous injuries.
- Unbreached games in three straight Premier League games
- 385 minutes without allowing a goal
- Only a handful of concessions in 12 games across every tournament
Former players and analysts have labeled Arteta's men as a "powerhouse, looking hard to stop" with the whole club now functioning with confidence and determination.
