There's little doubt why Arsenal stand as many people's favorites to win the Premier League during this term.
Consider their performances against Fulham and Crystal Palace compared to those same matches in the previous campaign.
The Gunners have beaten all of them in the current season, but dropped 10 points across those games as they dropped off in the title race previously.
Defensive Prowess
Arsenal's defensive strength is a primary factor why they are looking well positioned to at last realize their title goal.
They stand first for clean sheets (6), goals conceded (3), opposition efforts (72), dangerous chances allowed (19) and expected goals against (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 Expertise
Their effectiveness from free kicks is well known, but competing clubs still don't know how to contain the Gunners from these chances.
They have registered 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 perform multiple roles now. The whole team has a intimidation presence. People are just fearful of them and it is wonderful to see."
Championship Pedigree
What is even more remarkable about Arsenal's beginning to the campaign is they have also faced Manchester United, Liverpool and Newcastle United at opposition grounds and Manchester City on home turf - and are still leading by four at the top.
While they maintain victories, their traditional rivals are struggling. This marks the first time 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 expectations was on head coach Mikel Arteta at the beginning, having invested around £250m on eight summer additions in search of that coveted first title since 2004.
But the business has so far paid off in impressive fashion, with his side second top scorers in the league and having the most resilient defense, despite numerous injuries.
- Unbreached games in each of their last three Premier League games
- Nearly 6.5 hours without letting in a goal
- Only a trio of goals in 12 games across various contests
Former players and experts have described Arteta's men as a "powerhouse, looking challenging to stop" with the whole club now operating with belief and determination.
