It's obvious why Arsenal have become countless pundits' favorites to claim the Premier League during this term.
Consider their results against Fulham and Crystal Palace versus those same matches last season.
The Gunners have beaten all of them during this campaign, but surrendered 10 points across those games as they dropped off in the title race last season.
Defensive Prowess
Arsenal's defensive strength is a key reason why they are appearing strong to at last realize their title ambition.
They rank top for unbreached games (6), goals allowed (3), opposition efforts (72), quality opportunities against (19) and xGA (5.3).
The defensive partnership of Gabriel and William Saliba is possibly the finest in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Set-Piece Expertise
Their danger from dead balls is highly documented, but rival sides still don't know how to neutralize the Gunners from these opportunities.
They have scored 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 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 Claims
What is even more remarkable about Arsenal's start to the campaign is they have also played Manchester United, Liverpool and Newcastle United on the road and Manchester City at home - and are still four points clear at the top.
While they keep winning, their traditional rivals aren't faring so well. 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 scrutiny was on manager Mikel Arteta at the start, having spent around £250m on eight summer signings in quest of that long-awaited first title since 2004.
But the business has so far paid off in style, with his side one of the most prolific attacks in the league and having the most resilient defense, despite numerous injuries.
- Unbreached games in three straight Premier League games
- Over six hours without conceding a goal
- Only three goals in 12 games across all competitions
Former players and experts have described Arteta's men as a "juggernaut, looking difficult to stop" with the whole club now performing with conviction and purpose.
