There's little doubt why Arsenal have become many people's preferred choice to win the Premier League in the current campaign.
Look at their performances against Newcastle and Crystal Palace compared to those same 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 last season.
Impenetrable Defense
Arsenal's defensive strength is a primary factor why they are seeming ready to finally fulfil their title ambition.
They rank top for clean sheets (6), goals conceded (3), attempts against (72), shots on target faced (19) and anticipated concessions (5.3).
The center-back duo of Gabriel and William Saliba is potentially the best in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Set-Piece Expertise
Their effectiveness from free kicks is well known, but competing clubs still find it difficult to stop the Gunners from these chances.
They have notched 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 excel in various aspects now. The whole team has a intimidation presence. People are just afraid of them and it is great to see."
Championship Credentials
What is especially notable about Arsenal's commencement to the campaign is they have also encountered 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 keep winning, their historic competitors aren't faring so well. This marks the initial occasion 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 scrutiny was on boss Mikel Arteta at the outset, having invested around £250m on eight summer signings in quest of that long-awaited first title since 2004.
But the investment has so far proven successful in impressive fashion, with his side second top scorers in the league and possessing the most resilient defense, despite several injuries.
- Clean sheets in each of their last three Premier League games
- 385 minutes without conceding a goal
- Only a handful of concessions in 12 games across various contests
Former players and experts have labeled Arteta's men as a "unstoppable force, looking difficult to stop" with the whole club now performing with confidence and purpose.
