There's little doubt why Arsenal are now countless pundits' favorites to win the Premier League during this term.
Examine their outcomes against West Ham and Crystal Palace compared to those identical matches in the previous campaign.
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.
Defensive Prowess
Arsenal's defensive strength is a crucial element why they are seeming ready to finally fulfil their title ambition.
They rank top for shutouts (6), goals allowed (3), attempts against (72), shots on target faced (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is arguably the best in the league, with Arsenal keeping 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 struggle to neutralize 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 resulting from these situations.
"Arsenal can perform multiple roles now. The whole team has a fear factor. People are just wary of them and it is great to see."
Championship Pedigree
What is even more remarkable 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 ahead by four points at the top.
While they keep winning, their traditional rivals face difficulties. 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 boss Mikel Arteta at the beginning, having spent around £250m on eight summer signings in quest of that coveted first title since 2004.
But the investment has so far proven successful in impressive fashion, with his side one of the most prolific attacks in the league and possessing the tightest defense, despite multiple injuries.
- Shutouts 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 pundits have characterized Arteta's men as a "powerhouse, looking challenging to stop" with the whole club now performing with confidence and determination.
