The Gunners went in to the game having won 11 of their previous 13 Premier League clashes and holding the best points-per-game ratio of any English top-flight team in 2015.
A number of factors, such as Olivier Giroud and the inclusion of Francis Coquelin, have contributed to the Gunners' top form, yet the most impressive aspect is their performances against fellow top teams.
Victories over Manchester City at the Etihad and Manchester United in the FA Cup increased confidence, and their latest triumph over the Reds speaks volumes about their sudden improvement.
In such form, and with leaders Chelsea in sight, many observers are talking up a late title push, though Bellerin and Giroud remain philosophical on the idea of toppling the Blues.
"The team is definitely doing really well but we are just looking game by game to do the best we can and get as many points as we can," Bellerin told the BBC.
Giroud added: "We want to finish strongly but we have to take it game by game and focus on ourselves before looking at Chelsea and Man City's results.
“We want to win every single game and then we'll see what happens.”
Can Arsenal win the title this season?
With just seven games and 21 points remaining, Arsenal’s maximum possible points haul for this campaign is only 84 – a tally which would only have won the league once in the past decade.
They would need Jose Mourinho’s Chelsea side to suffer a catastrophic wobble and, given their form, the likelihood of that happening is extremely slim.
The Blues still have a game in hand over their competitors, and while only momentarily four points clear of second place, there is just too much quality in their squad to envisage a late fall.
