There's little doubt why Arsenal have become countless pundits' preferred choice to claim the Premier League this season.
Examine their results against Newcastle and Crystal Palace versus those identical matches in the previous campaign.
The Gunners have beaten all of them during this campaign, but lost 10 points across those games as they faded in the title race last season.
Impenetrable Defense
Arsenal's defensive solidity is a key reason why they are looking well positioned to finally fulfil their title target.
They rank top for shutouts (6), goals conceded (3), attempts against (72), quality opportunities against (19) and expected goals against (5.3).
The defensive partnership of Gabriel and William Saliba is arguably the finest in the league, with Arsenal keeping a clean sheet in six of their first nine games.
Set-Piece Mastery
Their danger from dead balls is widely recognized, but competing clubs still struggle to neutralize the Gunners from these opportunities.
They have registered 11 times from set-pieces in the league, two more 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 afraid of them and it is excellent to see."
Title 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 at home - and are still leading by four at the top.
While they continue triumphing, their traditional rivals face difficulties. This marks the premier instance 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 expectations was on head coach Mikel Arteta at the beginning, having invested around £250m on eight summer additions in pursuit 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 having the strongest defense, despite multiple injuries.
- Unbreached games in three straight Premier League games
- Over six hours without conceding a goal
- Only a trio of goals in 12 games across every tournament
Former players and experts have labeled Arteta's men as a "juggernaut, looking challenging to stop" with the whole club now performing with conviction and determination.
