There's no doubt why Arsenal are now countless pundits' top picks to claim the Premier League during this term.
Look at their performances against Newcastle and Crystal Palace in contrast with those equivalent matches in the previous campaign.
The Gunners have overcome all of them during this campaign, but lost 10 points across those games as they dropped off in the title race last season.
Impenetrable Backline
Arsenal's defensive strength is a key reason why they are looking well positioned to at last realize their title target.
They stand first for shutouts (6), goals allowed (3), shots faced (72), shots on target faced (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is possibly the finest in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Dead-Ball Superiority
Their effectiveness from free kicks is widely recognized, but competing clubs still don't know how to neutralize the Gunners from these situations.
They have notched 11 times from set-pieces in the league, two more than any other side, with 69% of their goals resulting from these situations.
"Arsenal can excel in various aspects now. The whole team has a fear factor. People are just wary of them and it is great to see."
Title Credentials
What is especially impressive 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 leading by four at the top.
While they keep winning, their traditional rivals aren't faring so well. This marks the first time 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 boss Mikel Arteta at the beginning, having allocated around £250m on eight summer additions in quest of that coveted first title since 2004.
But the investment has so far paid off in impressive fashion, with his side one of the most prolific attacks in the league and boasting the most resilient defense, despite numerous injuries.
- Shutouts in each of their last three Premier League games
- Nearly 6.5 hours without conceding a goal
- Only a handful of concessions in 12 games across all competitions
Former players and experts have characterized Arteta's men as a "unstoppable force, looking hard to stop" with the whole club now performing with conviction and determination.
