There's little doubt why Arsenal are now countless pundits' top picks to claim the Premier League this season.
Examine their performances against West Ham and Crystal Palace in contrast with those equivalent matches last season.
The Gunners have defeated all of them during this campaign, but dropped 10 points across those games as they faded in the title race previously.
Impenetrable Defense
Arsenal's backline resilience is a primary factor why they are looking well positioned to finally fulfil their title goal.
They rank top for clean sheets (6), goals allowed (3), attempts against (72), shots on target faced (19) and anticipated concessions (5.3).
The central defensive pairing 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 Proficiency
Their danger from dead balls is highly documented, but rival sides still struggle to stop the Gunners from these chances.
They have notched 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 excel in various aspects now. The whole team has a fear factor. People are just fearful of them and it is wonderful to see."
Championship Pedigree
What is even more remarkable about Arsenal's commencement to the campaign is they have also played Manchester United, Liverpool and Newcastle United away from home and Manchester City in their own stadium - 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 premier instance 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 scrutiny was on boss Mikel Arteta at the outset, having invested around £250m on eight summer additions in pursuit of that coveted first title since 2004.
But the business has so far paid off in style, with his side second top scorers in the league and having the tightest defense, despite numerous injuries.
- Shutouts in three consecutive Premier League games
- 385 minutes without letting in a goal
- Only three goals in 12 games across all competitions
Former players and pundits have labeled Arteta's men as a "powerhouse, looking challenging to stop" with the whole club now operating with belief and determination.
