There's little doubt why Arsenal are now many people's top picks to claim the Premier League in the current campaign.
Examine their results against West Ham and Crystal Palace versus those same matches during the prior term.
The Gunners have defeated all of them this time around, but dropped 10 points across those games as they fell away in the title race previously.
Impenetrable Rearguard
Arsenal's backline resilience is a key reason why they are seeming ready to finally fulfil their title target.
They lead the league for shutouts (6), shots let in (3), shots faced (72), dangerous chances allowed (19) and xGA (5.3).
The center-back duo of Gabriel and William Saliba is possibly the best in the league, with Arsenal maintaining a clean sheet in six of their first nine games.
Set-Piece Expertise
Their effectiveness from free kicks is well known, but opposition teams 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 perform multiple roles now. The whole team has a intimidation presence. People are just fearful of them and it is great to see."
Title Claims
What is especially remarkable about Arsenal's beginning to the campaign is they have also played Manchester United, Liverpool and Newcastle United on the road and Manchester City at home - and are still leading by four at the top.
While they maintain victories, their long-standing opponents face difficulties. This marks the first time at this stage 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 head coach Mikel Arteta at the outset, having allocated around £250m on eight summer acquisitions in quest of that elusive first title since 2004.
But the spending has so far proven successful in remarkable manner, with his side among the highest scorers in the league and having the strongest defense, despite multiple injuries.
- Clean sheets in each of their last three Premier League games
- Nearly 6.5 hours without allowing a goal
- Only a trio of goals in 12 games across every tournament
Former players and pundits have characterized Arteta's men as a "unstoppable force, looking hard to stop" with the whole club now operating with confidence and resolve.
