It's obvious why Arsenal have become countless pundits' favorites to secure the Premier League in the current campaign.
Examine their results against West Ham and Crystal Palace versus those same matches last season.
The Gunners have defeated all of them during this campaign, but lost 10 points across those games as they faded in the title race last season.
Defensive Strength
Arsenal's defensive strength is a primary factor why they are appearing strong to ultimately achieve their title target.
They stand first for shutouts (6), goals allowed (3), shots faced (72), dangerous chances allowed (19) and xGA (5.3).
The central defensive pairing of Gabriel and William Saliba is arguably the best 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 well known, but competing clubs still don't know how to contain 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 perform multiple roles now. The whole team has a daunting aura. People are just wary of them and it is wonderful to see."
Championship Pedigree
What is particularly remarkable about Arsenal's beginning to the campaign is they have also played 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 historic competitors are struggling. This marks the first time 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 pressure was on head coach Mikel Arteta at the outset, having spent around £250m on eight summer acquisitions in search of that elusive first title since 2004.
But the business has so far proven successful in remarkable manner, with his side second top scorers in the league and having the tightest defense, despite numerous injuries.
- Shutouts in each of their last three Premier League games
- Nearly 6.5 hours without letting in a goal
- Only three goals in 12 games across every tournament
Former players and pundits have described Arteta's men as a "powerhouse, looking hard to stop" with the whole club now functioning with belief and resolve.
