There's no doubt why Arsenal are now many people's favorites to win the Premier League this season.
Consider their performances against West Ham and Crystal Palace versus those same matches in the previous campaign.
The Gunners have overcome all of them during this campaign, but dropped 10 points across those games as they faded in the title race previously.
Defensive Strength
Arsenal's defensive strength is a primary factor why they are seeming ready to finally fulfil their title ambition.
They stand first for clean sheets (6), goals conceded (3), shots faced (72), quality opportunities against (19) and expected goals against (5.3).
The defensive partnership of Gabriel and William Saliba is potentially the strongest in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Set-Piece Mastery
Their effectiveness from free kicks is well known, but rival sides still struggle to neutralize the Gunners from these opportunities.
They have notched 11 times from set-pieces in the league, a couple extra than any other side, with 69% of their goals resulting from these situations.
"Arsenal can do a bit of everything now. The whole team has a fear factor. People are just fearful of them and it is excellent to see."
Championship Claims
What is even more remarkable about Arsenal's start to the campaign is they have also encountered Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City on home turf - and are still ahead by four points at the top.
While they maintain victories, their historic competitors are struggling. 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 expectations was on boss Mikel Arteta at the start, having invested around £250m on eight summer acquisitions in pursuit of that elusive first title since 2004.
But the spending has so far paid off in remarkable manner, with his side among the highest scorers in the league and possessing the tightest defense, despite multiple injuries.
- Unbreached games in three straight Premier League games
- 385 minutes without conceding a goal
- Only a handful of concessions in 12 games across every tournament
Former players and experts have described Arteta's men as a "juggernaut, looking hard to stop" with the whole club now functioning with conviction and determination.
