There's no doubt why Arsenal have become countless pundits' preferred choice to secure the Premier League in the current campaign.
Look at their results against West Ham and Crystal Palace in contrast with those equivalent matches in the previous campaign.
The Gunners have overcome all of them in the current season, but lost 10 points across those games as they dropped off in the title race last season.
Impenetrable Rearguard
Arsenal's defensive strength is a primary factor why they are seeming ready to at last realize their title target.
They rank top for shutouts (6), shots let in (3), shots faced (72), quality opportunities against (19) and anticipated concessions (5.3).
The center-back duo of Gabriel and William Saliba is possibly the finest in the league, with Arsenal recording a clean sheet in six of their first nine games.
Dead-Ball Dominance
Their effectiveness from free kicks is well known, but competing clubs still struggle to neutralize the Gunners from these opportunities.
They have registered 11 times from set-pieces in the league, two more 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 afraid of them and it is great to see."
Title Claims
What is especially 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 at home - and are still leading by four 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 scrutiny was on manager Mikel Arteta at the beginning, having allocated around £250m on eight summer acquisitions in search of that elusive first title since 2004.
But the business has so far proven successful in style, with his side among the highest scorers in the league and boasting the strongest defense, despite numerous injuries.
- Shutouts in each of their last three Premier League games
- Nearly 6.5 hours without conceding a goal
- Only a trio of goals in 12 games across all competitions
Former players and analysts have described Arteta's men as a "juggernaut, looking hard to stop" with the whole club now functioning with conviction and determination.
