It's evident why Arsenal stand as countless pundits' top picks to win the Premier League this season.
Look at their outcomes against West Ham and Crystal Palace versus those identical matches last season.
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 previously.
Impenetrable Rearguard
Arsenal's backline resilience is a key reason why they are seeming ready to at last realize their title goal.
They lead the league for clean sheets (6), goals allowed (3), opposition efforts (72), shots on target faced (19) and xGA (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.
Dead-Ball Dominance
Their threat from set-pieces is highly documented, but competing clubs still find it difficult to neutralize the Gunners from these situations.
They have registered 11 times from set-pieces in the league, two more 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 afraid of them and it is excellent to see."
Title Potential
What is even more remarkable about Arsenal's start to the campaign is they have also faced Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City on home turf - 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 stage 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 outset, having allocated around £250m on eight summer acquisitions in search of that long-awaited first title since 2004.
But the spending has so far paid off in impressive fashion, with his side second top scorers in the league and having the tightest defense, despite multiple injuries.
- Clean sheets in three consecutive Premier League games
- Nearly 6.5 hours without allowing a goal
- Only three goals in 12 games across various contests
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 resolve.
