It's clear why Arsenal are now many people's preferred choice to secure the Premier League during this term.
Examine their results against Fulham and Crystal Palace in contrast with those same matches last season.
The Gunners have defeated all of them during this campaign, but lost 10 points across those games as they dropped off in the title race previously.
Impenetrable Rearguard
Arsenal's defensive strength is a key reason why they are looking well positioned to ultimately achieve their title target.
They lead the league for unbreached games (6), shots let in (3), opposition efforts (72), shots on target faced (19) and anticipated concessions (5.3).
The center-back duo 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.
Dead-Ball Superiority
Their threat from set-pieces is highly documented, but opposition teams still don't know how to stop the Gunners from these opportunities.
They have scored 11 times from set-pieces in the league, several additional than any other side, with 69% of their goals coming from these situations.
"Arsenal can excel in various aspects now. The whole team has a fear factor. People are just afraid of them and it is wonderful to see."
Championship Claims
What is even more impressive about Arsenal's commencement to the campaign is they have also faced Manchester United, Liverpool and Newcastle United on the road and Manchester City on home turf - and are still leading by four at the top.
While they maintain victories, their long-standing opponents 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 beginning, having spent around £250m on eight summer additions in pursuit of that elusive first title since 2004.
But the spending has so far paid off in style, with his side second top scorers in the league and boasting the tightest defense, despite numerous injuries.
- Shutouts in three straight Premier League games
- Over six hours without allowing a goal
- Only three goals in 12 games across all competitions
Former players and experts have described Arteta's men as a "juggernaut, looking hard to stop" with the whole club now functioning with belief and purpose.
