It's clear why Arsenal stand as many people's favorites to win the Premier League this season.
Examine their results against West Ham and Crystal Palace versus those identical matches last season.
The Gunners have defeated all of them in the current season, but lost 10 points across those games as they faded in the title race previously.
Defensive Strength
Arsenal's backline resilience is a key reason why they are seeming ready to ultimately achieve their title ambition.
They lead the league for shutouts (6), goals allowed (3), opposition efforts (72), quality opportunities against (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is arguably the strongest in the league, with Arsenal maintaining a clean sheet in six of their first nine games.
Set-Piece Mastery
Their effectiveness from free kicks is widely recognized, but opposition teams still find it difficult to neutralize the Gunners from these opportunities.
They have scored 11 times from set-pieces in the league, a couple extra than any other side, with 69% of their goals coming from these situations.
"Arsenal can excel in various aspects now. The whole team has a fear factor. People are just fearful of them and it is great to see."
Championship Credentials
What is especially remarkable about Arsenal's commencement to the campaign is they have also played Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City in their own stadium - and are still four points clear at the top.
While they continue triumphing, 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 scrutiny was on manager Mikel Arteta at the start, having spent around £250m on eight summer acquisitions in search of that elusive first title since 2004.
But the investment has so far paid off in remarkable manner, with his side second top scorers in the league and boasting the tightest defense, despite several injuries.
- Unbreached games in each of their last three Premier League games
- 385 minutes without letting in a goal
- Only three goals in 12 games across all competitions
Former players and experts have labeled Arteta's men as a "powerhouse, looking hard to stop" with the whole club now performing with confidence and purpose.
