There's little doubt why Arsenal stand as many people's favorites to win the Premier League during this term.
Look at their results against West Ham and Crystal Palace in contrast with those same matches last season.
The Gunners have defeated all of them in the current season, but surrendered 10 points across those games as they fell away in the title race previously.
Impenetrable Rearguard
Arsenal's defensive strength is a crucial element why they are appearing strong to at last realize their title target.
They stand first for shutouts (6), goals conceded (3), attempts against (72), quality opportunities against (19) and anticipated concessions (5.3).
The center-back duo of Gabriel and William Saliba is potentially the best in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Dead-Ball Excellence
Their danger from dead balls is highly documented, but opposition teams still don't know how to contain the Gunners from these situations.
They have notched 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 daunting aura. People are just fearful of them and it is excellent to see."
Championship Credentials
What is particularly impressive about Arsenal's beginning to the campaign is they have also played Manchester United, Liverpool and Newcastle United on the road and Manchester City on home turf - and are still leading by four at the top.
While they continue triumphing, their historic competitors aren't faring so well. This marks the premier instance 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 pressure was on boss Mikel Arteta at the outset, having allocated around £250m on eight summer signings in quest of that long-awaited first title since 2004.
But the business has so far yielded results in remarkable manner, with his side one of the most prolific attacks in the league and possessing the most resilient defense, despite several injuries.
- Clean sheets in three straight Premier League games
- Over six hours without conceding a goal
- Only three goals in 12 games across various contests
Former players and experts have described Arteta's men as a "powerhouse, looking difficult to stop" with the whole club now operating with conviction and resolve.
