There's little doubt why Arsenal have become many people's favorites to secure the Premier League during this term.
Consider their outcomes against West Ham and Crystal Palace versus those identical matches in the previous campaign.
The Gunners have beaten all of them this time around, but dropped 10 points across those games as they dropped off in the title race previously.
Defensive Strength
Arsenal's defensive strength is a primary factor why they are seeming ready to at last realize their title goal.
They lead the league for shutouts (6), shots let in (3), shots faced (72), dangerous chances allowed (19) and anticipated concessions (5.3).
The center-back duo of Gabriel and William Saliba is arguably the finest 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 opposition teams still struggle to neutralize the Gunners from these opportunities.
They have registered 11 times from set-pieces in the league, a couple extra than any other side, with 69% of their goals resulting 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 Pedigree
What is especially notable about Arsenal's commencement to the campaign is they have also encountered Manchester United, Liverpool and Newcastle United away from home and Manchester City at home - and are still leading by four at the top.
While they maintain victories, their long-standing opponents face difficulties. This marks the first time 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 manager Mikel Arteta at the beginning, having invested around £250m on eight summer signings in search of that coveted first title since 2004.
But the business has so far paid off in impressive fashion, with his side second top scorers in the league and possessing the strongest defense, despite numerous injuries.
- Shutouts in three straight Premier League games
- Over six hours without letting in a goal
- Only a trio of goals in 12 games across every tournament
Former players and experts have characterized Arteta's men as a "unstoppable force, looking challenging to stop" with the whole club now operating with confidence and resolve.
