There's little doubt why Arsenal are now countless pundits' top picks to win the Premier League this season.
Consider their performances against West Ham and Crystal Palace in contrast with those same matches in the previous campaign.
The Gunners have defeated all of them in the current season, but dropped 10 points across those games as they dropped off in the title race last season.
Defensive Strength
Arsenal's defensive solidity is a primary factor why they are appearing strong to finally fulfil their title ambition.
They lead the league for unbreached games (6), shots let in (3), shots faced (72), shots on target faced (19) and expected goals against (5.3).
The center-back duo of Gabriel and William Saliba is potentially the finest in the league, with Arsenal recording a clean sheet in six of their first nine games.
Set-Piece Expertise
Their danger from dead balls is well known, but opposition teams still find it difficult to contain the Gunners from these situations.
They have scored 11 times from set-pieces in the league, several additional 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 intimidation presence. People are just wary of them and it is great to see."
Title Credentials
What is particularly 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 in their own stadium - 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 scrutiny was on manager Mikel Arteta at the outset, having allocated around £250m on eight summer signings in pursuit of that elusive first title since 2004.
But the business has so far proven successful in impressive fashion, with his side one of the most prolific attacks in the league and possessing the strongest defense, despite several injuries.
- Unbreached games in each of their last three Premier League games
- Nearly 6.5 hours without letting in a goal
- Only a handful of concessions in 12 games across all competitions
Former players and analysts have characterized Arteta's men as a "powerhouse, looking challenging to stop" with the whole club now functioning with conviction and determination.
