There's little doubt why Arsenal stand as many people's favorites to claim the Premier League in the current campaign.
Consider their results against West Ham and Crystal Palace versus those identical matches in the previous campaign.
The Gunners have defeated all of them during this campaign, but surrendered 10 points across those games as they dropped off in the title race last season.
Impenetrable Rearguard
Arsenal's defensive solidity is a key reason why they are appearing strong to at last realize their title goal.
They lead the league for shutouts (6), goals allowed (3), shots faced (72), quality opportunities against (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is potentially the finest in the league, with Arsenal maintaining a clean sheet in six of their first nine games.
Set-Piece Mastery
Their danger from dead balls is highly documented, but opposition teams still find it difficult to neutralize the Gunners from these opportunities.
They have notched 11 times from set-pieces in the league, a couple extra than any other side, with 69% of their goals originating from these situations.
"Arsenal can perform multiple roles now. The whole team has a intimidation presence. People are just fearful of them and it is excellent to see."
Championship Pedigree
What is particularly impressive about Arsenal's start to the campaign is they have also played Manchester United, Liverpool and Newcastle United away from home and Manchester City at home - and are still ahead by four points at the top.
While they keep winning, their long-standing opponents aren't faring so well. This marks the initial occasion 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 pressure was on manager Mikel Arteta at the beginning, having allocated around £250m on eight summer acquisitions in quest of that long-awaited first title since 2004.
But the business has so far yielded results in impressive fashion, with his side among the highest scorers in the league and having the most resilient defense, despite numerous 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 all competitions
Former players and pundits have described Arteta's men as a "juggernaut, looking hard to stop" with the whole club now performing with confidence and purpose.
