It's clear why Arsenal have become countless pundits' favorites to win the Premier League during this term.
Consider their performances against West Ham and Crystal Palace in contrast with those same matches during the prior term.
The Gunners have overcome all of them in the current season, but surrendered 10 points across those games as they fell away in the title race in the prior campaign.
Impenetrable Rearguard
Arsenal's defensive strength is a crucial element why they are appearing strong to ultimately achieve their title ambition.
They rank top for shutouts (6), goals allowed (3), attempts against (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 maintaining a clean sheet in six of their first nine games.
Set-Piece Proficiency
Their effectiveness from free kicks is well known, but opposition teams still find it difficult to contain the Gunners from these situations.
They have notched 11 times from set-pieces in the league, several additional than any other side, with 69% of their goals resulting from these situations.
"Arsenal can do a bit of everything now. The whole team has a intimidation presence. People are just afraid of them and it is excellent to see."
Championship Claims
What is especially 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 on home turf - and are still leading by four at the top.
While they maintain victories, their historic competitors aren't faring so well. 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 pressure was on head coach Mikel Arteta at the start, having invested around £250m on eight summer signings in quest of that long-awaited first title since 2004.
But the investment has so far proven successful in remarkable manner, with his side second top scorers in the league and possessing the tightest defense, despite multiple injuries.
- Unbreached games in each of their last three Premier League games
- 385 minutes without letting in a goal
- Only a trio of goals in 12 games across various contests
Former players and analysts have labeled Arteta's men as a "juggernaut, looking challenging to stop" with the whole club now functioning with belief and purpose.
