There's no doubt why Arsenal stand as countless pundits' top picks to claim the Premier League this season.
Examine their results against West Ham and Crystal Palace compared to those equivalent matches in the previous campaign.
The Gunners have beaten all of them during this campaign, but surrendered 10 points across those games as they faded in the title race last season.
Defensive Prowess
Arsenal's backline resilience is a key reason why they are seeming ready to at last realize their title target.
They lead the league for clean sheets (6), shots let in (3), opposition efforts (72), shots on target faced (19) and expected goals against (5.3).
The center-back duo of Gabriel and William Saliba is arguably the best in the league, with Arsenal recording a clean sheet in six of their first nine games.
Set-Piece Mastery
Their threat from set-pieces is well known, but rival sides still find it difficult to contain the Gunners from these situations.
They have notched 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 perform multiple roles now. The whole team has a fear factor. People are just wary of them and it is great to see."
Championship Credentials
What is especially impressive about Arsenal's commencement to the campaign is they have also faced Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City at home - and are still four points clear at the top.
While they maintain victories, their traditional rivals aren't faring so well. This marks the first time 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 head coach Mikel Arteta at the start, having invested around £250m on eight summer acquisitions in quest of that elusive first title since 2004.
But the spending has so far paid off in remarkable manner, with his side among the highest scorers in the league and possessing the tightest defense, despite numerous injuries.
- Unbreached games in three straight Premier League games
- Nearly 6.5 hours without conceding a goal
- Only a handful of concessions in 12 games across all competitions
Former players and pundits have described Arteta's men as a "unstoppable force, looking difficult to stop" with the whole club now functioning with belief and purpose.
