Arsenal fans seemingly joined forces with their counterparts from Cologne to troll Tottenham Hotspur during their Europa League tie in Germany on Thursday night.
After the behaviour of visiting German fans came under the microscope during the pair's meeting back in September - which had to be delayed by an hour - the two sets of fans linked up in perfect harmony at the RheinEnergieStadion, although Spurs fans won't want to hear it.
In the video above captured by Arsenal Fan TV's @MrDtAFC , he claims that Arsenal and Cologne supporters can be heard chanting "Tottenham are s***!" to each other across the pitch.
The visiting fans - fresh from the Gunners' weekend victory in the north London derby - were obviously in fine voice during the first half, although their mood would soon have darkened.
A 62nd minute penalty from Sehrou Guirassy secured a 1-0 win for the hosts , although Arsenal have still qualified for the last-32 of the Europa League as group winners.
Tottenham, meanwhile, beat Borussia Dortmund 2-1 in Germany on Tuesday to secure top spot in their Champions League group.
