There's little doubt why Arsenal have become many people's top picks to win the Premier League this season.
Look at their performances 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 surrendered 10 points across those games as they faded in the title race in the prior campaign.
Defensive Dominance
Arsenal's backline resilience is a crucial element why they are appearing strong to ultimately achieve their title target.
They lead the league for unbreached games (6), shots let in (3), shots faced (72), dangerous chances allowed (19) and expected goals against (5.3).
The defensive partnership of Gabriel and William Saliba is possibly the best in the league, with Arsenal recording a clean sheet in six of their first nine games.
Set-Piece Mastery
Their effectiveness from free kicks is well known, but rival sides still struggle to neutralize the Gunners from these chances.
They have notched 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 do a bit of everything now. The whole team has a daunting aura. People are just fearful of them and it is excellent to see."
Championship Credentials
What is particularly impressive about Arsenal's start 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 leading by four at the top.
While they keep winning, their long-standing opponents aren't faring so well. This marks the premier instance 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 expectations was on boss Mikel Arteta at the beginning, having invested around £250m on eight summer acquisitions in search of that elusive first title since 2004.
But the investment has so far yielded results in style, with his side second top scorers in the league and having the strongest defense, despite multiple injuries.
- Unbreached games in three straight Premier League games
- 385 minutes without allowing a goal
- Only a trio of goals in 12 games across all competitions
Former players and pundits have described Arteta's men as a "juggernaut, looking difficult to stop" with the whole club now operating with belief and purpose.
