There's little doubt why Arsenal stand as countless pundits' favorites to claim the Premier League this season.
Consider their performances against Newcastle and Crystal Palace in contrast with those identical matches last season.
The Gunners have overcome all of them this time around, but lost 10 points across those games as they faded in the title race previously.
Impenetrable Defense
Arsenal's defensive solidity is a key reason why they are looking well positioned to finally fulfil their title target.
They stand first for shutouts (6), shots let in (3), attempts against (72), quality opportunities against (19) and xGA (5.3).
The defensive partnership of Gabriel and William Saliba is possibly the strongest 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 widely recognized, but competing clubs still struggle to stop the Gunners from these situations.
They have notched 11 times from set-pieces in the league, several additional than any other side, with 69% of their goals originating from these situations.
"Arsenal can excel in various aspects now. The whole team has a daunting aura. People are just wary of them and it is excellent to see."
Championship Pedigree
What is particularly notable about Arsenal's start to the campaign is they have also played Manchester United, Liverpool and Newcastle United on the road and Manchester City in their own stadium - and are still leading by four at the top.
While they continue triumphing, their historic competitors aren't faring so well. This marks the initial occasion 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 expectations was on boss Mikel Arteta at the outset, having invested around £250m on eight summer acquisitions in pursuit of that coveted first title since 2004.
But the spending has so far yielded results in style, with his side one of the most prolific attacks in the league and having the tightest defense, despite numerous injuries.
- Shutouts in three straight Premier League games
- Over six hours without letting in a goal
- Only a trio of goals in 12 games across all competitions
Former players and pundits have described Arteta's men as a "powerhouse, looking difficult to stop" with the whole club now performing with conviction and purpose.
