There's no doubt why Arsenal are now many people's favorites to claim the Premier League in the current campaign.
Consider their outcomes against West Ham and Crystal Palace compared to those same matches last season.
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 previously.
Impenetrable Rearguard
Arsenal's defensive strength is a crucial element why they are seeming ready to at last realize their title goal.
They stand first for unbreached games (6), goals allowed (3), shots faced (72), shots on target faced (19) and xGA (5.3).
The defensive partnership 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 Proficiency
Their danger from dead balls is widely recognized, but rival sides 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 resulting from these situations.
"Arsenal can perform multiple roles now. The whole team has a fear factor. People are just fearful of them and it is great to see."
Title Claims
What is especially impressive about Arsenal's beginning to the campaign is they have also faced Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City on home turf - and are still four points clear at the top.
While they continue triumphing, their long-standing opponents are struggling. This marks the first time 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 head coach Mikel Arteta at the beginning, having invested around £250m on eight summer signings in pursuit of that elusive first title since 2004.
But the investment has so far paid off in style, with his side one of the most prolific attacks in the league and having the most resilient defense, despite several injuries.
- Shutouts in three straight Premier League games
- Over six hours without letting in a goal
- Only a handful of concessions in 12 games across all competitions
Former players and pundits have labeled Arteta's men as a "juggernaut, looking difficult to stop" with the whole club now operating with belief and purpose.
