There's little doubt why Arsenal have become countless pundits' favorites to secure the Premier League during this term.
Consider their results against West Ham and Crystal Palace versus those identical matches during the prior term.
The Gunners have defeated all of them this time around, but dropped 10 points across those games as they dropped off in the title race last season.
Impenetrable Backline
Arsenal's defensive solidity is a crucial element why they are looking well positioned to finally fulfil their title target.
They lead the league for shutouts (6), goals allowed (3), opposition efforts (72), shots on target faced (19) and expected goals against (5.3).
The defensive partnership of Gabriel and William Saliba is arguably the finest in the league, with Arsenal maintaining a clean sheet in six of their first nine games.
Set-Piece Proficiency
Their effectiveness from free kicks is well known, but competing clubs still don't know how to contain the Gunners from these opportunities.
They have registered 11 times from set-pieces in the league, two more than any other side, with 69% of their goals originating from these situations.
"Arsenal can do a bit of everything now. The whole team has a daunting aura. People are just afraid of them and it is wonderful to see."
Title Credentials
What is particularly impressive about Arsenal's beginning to the campaign is they have also played Manchester United, Liverpool and Newcastle United away from home and Manchester City on home turf - and are still leading by four at the top.
While they maintain victories, their historic competitors 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 pressure was on manager Mikel Arteta at the start, having invested around £250m on eight summer acquisitions in pursuit of that coveted first title since 2004.
But the spending has so far paid off in impressive fashion, with his side among the highest scorers in the league and having the strongest defense, despite multiple injuries.
- Clean sheets in three consecutive Premier League games
- Nearly 6.5 hours without allowing a goal
- Only a trio of goals in 12 games across various contests
Former players and pundits have labeled Arteta's men as a "unstoppable force, looking difficult to stop" with the whole club now performing with confidence and purpose.
