There's little doubt why Arsenal stand as countless pundits' top picks to win the Premier League during this term.
Consider their outcomes against Fulham and Crystal Palace in contrast with those identical 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 previously.
Impenetrable Backline
Arsenal's defensive strength is a primary factor why they are appearing strong to ultimately achieve their title target.
They stand first for clean sheets (6), goals conceded (3), opposition efforts (72), quality opportunities against (19) and anticipated concessions (5.3).
The center-back duo of Gabriel and William Saliba is possibly the finest in the league, with Arsenal recording a clean sheet in six of their first nine games.
Set-Piece Proficiency
Their threat from set-pieces is well known, but rival sides still struggle to neutralize the Gunners from these chances.
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 excel in various aspects now. The whole team has a intimidation presence. People are just fearful of them and it is excellent to see."
Championship Pedigree
What is particularly impressive about Arsenal's beginning to the campaign is they have also encountered 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 maintain victories, their historic competitors are struggling. This marks the first time at this point 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 start, having spent around £250m on eight summer signings in search of that coveted first title since 2004.
But the investment has so far yielded results in remarkable manner, with his side among the highest scorers in the league and possessing the tightest defense, despite several injuries.
- Clean sheets in each of their last three Premier League games
- Over six hours without letting in a goal
- Only a handful of concessions in 12 games across all competitions
Former players and experts have described Arteta's men as a "unstoppable force, looking challenging to stop" with the whole club now functioning with belief and purpose.
