There's little doubt why Arsenal are now many people's preferred choice to claim the Premier League this season.
Look at their results against West Ham and Crystal Palace compared to those same matches during the prior term.
The Gunners have overcome all of them this time around, but surrendered 10 points across those games as they dropped off in the title race in the prior campaign.
Impenetrable Rearguard
Arsenal's backline resilience is a key reason why they are looking well positioned to finally fulfil their title goal.
They rank top for shutouts (6), goals allowed (3), attempts against (72), dangerous chances allowed (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is potentially the strongest in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Set-Piece Mastery
Their effectiveness from free kicks is highly documented, but competing clubs still don't know how to contain the Gunners from these situations.
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 intimidation presence. People are just afraid of them and it is great to see."
Title Potential
What is particularly notable about Arsenal's beginning to the campaign is they have also encountered Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City in their own stadium - and are still leading by four at the top.
While they keep winning, their traditional rivals aren't faring so well. This marks the initial occasion at this juncture of the season since 1992 that none of Manchester City and United, Liverpool or Chelsea are in the Premier League top four.
The scrutiny was on manager Mikel Arteta at the start, having allocated around £250m on eight summer signings in pursuit 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 strongest defense, despite numerous injuries.
- Unbreached games in three straight Premier League games
- Nearly 6.5 hours without conceding a goal
- Only three goals in 12 games across every tournament
Former players and experts have described Arteta's men as a "powerhouse, looking hard to stop" with the whole club now functioning with confidence and resolve.
