There's no doubt why Arsenal have become countless pundits' favorites to secure the Premier League in the current campaign.
Look at their results against West Ham and Crystal Palace versus those equivalent matches in the previous campaign.
The Gunners have beaten all of them during this campaign, but lost 10 points across those games as they fell away in the title race previously.
Impenetrable Rearguard
Arsenal's defensive solidity is a crucial element why they are looking well positioned to at last realize their title ambition.
They lead the league for shutouts (6), goals conceded (3), shots faced (72), shots on target faced (19) and anticipated concessions (5.3).
The central defensive pairing of Gabriel and William Saliba is potentially the finest in the league, with Arsenal maintaining a clean sheet in six of their first nine games.
Set-Piece Proficiency
Their threat from set-pieces is highly documented, but competing clubs still find it difficult to contain the Gunners from these situations.
They have notched 11 times from set-pieces in the league, a couple extra 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 intimidation presence. People are just wary of them and it is excellent to see."
Championship Pedigree
What is even more notable about Arsenal's start to the campaign is they have also played Manchester United, Liverpool and Newcastle United away from home and Manchester City at home - and are still leading by four at the top.
While they keep winning, their historic competitors aren't faring so well. This marks the premier instance 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 spent 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 one of the most prolific attacks in the league and having the strongest defense, despite multiple injuries.
- Unbreached games in three straight Premier League games
- Nearly 6.5 hours without letting in a goal
- Only three goals in 12 games across various contests
Former players and experts have labeled Arteta's men as a "unstoppable force, looking challenging to stop" with the whole club now operating with belief and purpose.
