There's little doubt why Arsenal are now countless pundits' top picks to secure the Premier League in the current campaign.
Examine their results against West Ham and Crystal Palace versus those identical matches in the previous campaign.
The Gunners have defeated all of them this time around, but lost 10 points across those games as they faded in the title race in the prior campaign.
Defensive Strength
Arsenal's backline resilience is a primary factor why they are appearing strong to ultimately achieve their title goal.
They lead the league for shutouts (6), goals conceded (3), attempts against (72), shots on target faced (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is arguably the finest in the league, with Arsenal keeping 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 find it difficult to neutralize the Gunners from these chances.
They have registered 11 times from set-pieces in the league, several additional than any other side, with 69% of their goals coming 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 remarkable about Arsenal's start to the campaign is they have also encountered 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 long-standing opponents face difficulties. This marks the first time 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 pressure was on boss Mikel Arteta at the beginning, having invested around £250m on eight summer signings in quest of that long-awaited first title since 2004.
But the investment has so far paid off in remarkable manner, with his side among the highest scorers in the league and having the strongest defense, despite several injuries.
- Shutouts in three straight Premier League games
- Over six hours without conceding a goal
- Only a handful of concessions in 12 games across various contests
Former players and analysts have labeled Arteta's men as a "juggernaut, looking hard to stop" with the whole club now performing with belief and purpose.
