There's little doubt why Arsenal have become countless pundits' top picks to win the Premier League this season.
Look at their outcomes against West Ham and Crystal Palace in contrast with those identical matches last season.
The Gunners have beaten all of them during this campaign, but dropped 10 points across those games as they dropped off in the title race previously.
Impenetrable Backline
Arsenal's defensive strength is a primary factor why they are appearing strong to at last realize their title goal.
They lead the league for shutouts (6), goals conceded (3), attempts against (72), quality opportunities against (19) and expected goals against (5.3).
The center-back duo of Gabriel and William Saliba is possibly the strongest in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Set-Piece Expertise
Their threat from set-pieces is highly documented, but competing clubs still don't know how to contain the Gunners from these situations.
They have registered 11 times from set-pieces in the league, a couple extra 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 intimidation presence. People are just afraid of them and it is wonderful to see."
Title Credentials
What is even more remarkable about Arsenal's commencement to the campaign is they have also encountered 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 traditional rivals 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 scrutiny was on manager Mikel Arteta at the start, having invested around £250m on eight summer additions in pursuit of that long-awaited first title since 2004.
But the spending has so far proven successful in remarkable manner, with his side second top scorers in the league and boasting the strongest defense, despite numerous injuries.
- Unbreached games in each of their last three Premier League games
- Over six hours without conceding a goal
- Only three goals in 12 games across various contests
Former players and pundits have described Arteta's men as a "juggernaut, looking difficult to stop" with the whole club now performing with confidence and resolve.
