They're also unbeaten in their last eight games in all competitions, so the North Londoners will therefore head into their tie against Atletico Madrid full of confidence, particularly when factoring in that Los Rojiblancos have never won away to an English side in the group or league phase of the UCL.
Atleti have been poor on English shores
The closest they've come is earning two draws, but they've suffered three defeats in games in England, most notably a 4-0 loss to Chelsea 16 years ago this month.
In fact, Diego Simeone’s side have just one win from nine games against English sides in European competition (D2 L6) - a 1-0 win against Man Utd in 2022.
Along with Inter, Mikel Arteta's high flyers are the only team not to have conceded in the competition either, making Atleti's task at the Emirates Stadium doubly difficult.
Arsenal are ranked right at the top for xG against (0.85) in the Champions League, and have held their opponents to under one xG in seven of their 10 league-phase matches since the start of last season.
Saka bound to influence proceedings
All of that taken into account, and with the greatest respect to previous European opponents this season, Athletic Club and Olympiacos, Atleti should still represent the Gunners toughest test.
That's because of the top 10 sides in the table currently, the Spaniards have scored the second most goals (seven) along with city rivals Real Madrid - only Bayern Munich have more (eight) - whilst Arsenal have found the net on just four occasions, the second least in the top 10 (only Tottenham have scored less - 3).
Arsenal talisman, Bukayo Saka, has already been directly involved in 17 goals in 19 appearances in the Champions League (11 goals, six assists), and since he debuted in the competition in late 2023, only Raphinha has a better minutes-per-goal involvement (69) than Saka's 89, for those wingers that have played 500+ minutes.
Whilst it's therefore vital for Atleti to dilute the England international's influence, the Spaniards will be acutely aware that Arsenal's threat extends right across their front line and midfield three, so fluid have the Gunners become as an attacking unit.
Indeed, Gabriel Martinelli has been their most potent goalscoring weapon in the competition to date this season, scoring twice so far.
Alvarez the key for Atleti?
Los Rojiblancos have an attacking weapon of their own of course, and one who the North Londoners will know well from his time at Man City: Julian Alvarez.
The Argentinian has 13 goals in 11 UCL games since the start of the 2023-24 campaign, but his impact in this team extends to much more than just goals.
Alongside the effervescent Antoine Griezmann, both players are the conduits through which all good things come, and if Arsenal concentrate solely on the damage that the pair of World Cup winners can do, then Simeone has the raiding Marcos Llorente to add drive and desire into the mix for good measure.
Llorente could also be looked to, along with Conor Gallagher, to provide a repellant to an Arsenal side that like to ease through the gears in the middle of the park when possible.
Gallagher's seven interceptions are the most in the UCL this season by way of example, and by keeping tabs on the likes of Declan Rice and Martin Zubimendi, Atleti could actually force Arteta into altering his pre-match game plan entirely.
Not to mention that the visitors are also the top-ranked team in this season's competition for line-breaking passes (22), are third (out of 36 teams) for shot conversion (29%) and fourth for shots on target (16) - both significantly better than their opponents.
Head-to-head record favours the Spaniards
In fact, in almost every available metric (more passes, better accuracy etc), the Spaniards have been better than Arsenal in this season's competition, and when one considers how well-oiled the Gunners are as a passing outfit, that's a big surprise.
The head-to-head record also favours Atleti. The teams have met just twice before in official competition - in a two-legged Europa League semi-final in 2017/18.
Despite being down to 10 men for 80 minutes of the match, the Spaniards still hung on for a 1-1 draw at the Emirates and won the return 1-0 to advance to the final where they comprehensively despatched Marseille 3-0.
Simeone has the luxury of a virtually full-strength squad to choose from on Tuesday, whilst Arteta has to cope with the continued absences of Gabriel Jesus, Noni Madueke, Kai Havertz and Martin Odegaard.
