There's no doubt why Arsenal stand as many people's favorites to win the Premier League in the current campaign.
Look at their outcomes against West Ham and Crystal Palace in contrast with those identical matches in the previous campaign.
The Gunners have beaten all of them this time around, but lost 10 points across those games as they dropped off in the title race last season.
Impenetrable Backline
Arsenal's backline resilience is a primary factor why they are seeming ready to at last realize their title ambition.
They stand first for unbreached games (6), goals conceded (3), attempts against (72), dangerous chances allowed (19) and expected goals against (5.3).
The center-back duo 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 danger from dead balls is well known, but rival sides still don't know how to contain the Gunners from these opportunities.
They have registered 11 times from set-pieces in the league, two more than any other side, with 69% of their goals coming from these situations.
"Arsenal can do a bit of everything now. The whole team has a daunting aura. People are just afraid of them and it is excellent to see."
Title Claims
What is even more remarkable about Arsenal's beginning to the campaign is they have also faced Manchester United, Liverpool and Newcastle United away from home and Manchester City in their own stadium - and are still ahead by four points at the top.
While they continue triumphing, their long-standing opponents 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 beginning, having spent around £250m on eight summer additions in pursuit of that coveted first title since 2004.
But the business has so far paid off in impressive fashion, with his side one of the most prolific attacks in the league and having the most resilient defense, despite several injuries.
- Shutouts in three straight Premier League games
- Nearly 6.5 hours without allowing a goal
- Only a handful of concessions in 12 games across all competitions
Former players and pundits have described Arteta's men as a "powerhouse, looking difficult to stop" with the whole club now operating with confidence and purpose.
