It's clear why Arsenal are now many people's top picks to claim the Premier League this season.
Look at their results against West Ham and Crystal Palace compared to those identical matches in the previous campaign.
The Gunners have overcome all of them in the current season, but surrendered 10 points across those games as they faded in the title race last season.
Impenetrable Rearguard
Arsenal's backline resilience is a crucial element why they are appearing strong to ultimately achieve their title target.
They stand first for shutouts (6), goals allowed (3), attempts against (72), quality opportunities against (19) and anticipated concessions (5.3).
The defensive partnership of Gabriel and William Saliba is arguably the strongest in the league, with Arsenal recording a clean sheet in six of their first nine games.
Dead-Ball Dominance
Their effectiveness from free kicks is widely recognized, but competing clubs still find it difficult to neutralize 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 perform multiple roles now. The whole team has a fear factor. People are just fearful of them and it is great to see."
Championship Claims
What is even more impressive about Arsenal's beginning to the campaign is they have also played Manchester United, Liverpool and Newcastle United away from home and Manchester City on home turf - and are still ahead by four points at the top.
While they maintain victories, their traditional rivals face difficulties. 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 pressure was on boss Mikel Arteta at the beginning, having invested around £250m on eight summer acquisitions in pursuit of that long-awaited first title since 2004.
But the business has so far paid off in remarkable manner, with his side second top scorers in the league and having the most resilient defense, despite numerous injuries.
- Shutouts 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 every tournament
Former players and experts have characterized Arteta's men as a "powerhouse, looking challenging to stop" with the whole club now functioning with conviction and determination.
