Victory at Steaua Bucharest last night made it nine straight wins for Arsenal last night.
That equals the record set by the Arsenal side which won the league unbeaten in 2003/2004.
Gunners boss Arsene Wenger, though, again stressed it was too early to draw comparisons.
Wenger said: "That is now our challenge - how long can we extend this run? How can we try to be inspired by that kind of consistency, but it is too early to compare a run like we did before.
"In 49 and nine, there is 40 games difference. Let's go step by step and try to win the next game, which is Sunderland at home."
