Feyenoord fans aimed a cheeky dig at Manchester United last night, as they prepared for a visit to City's Etihad Stadium.
Thousands of supporters from the Dutch club are in Manchester ahead of tonight's match with City in Champions League.
But it was United who received the brunt of their humour last night, as hordes of supporters were filmed singing 'You'll Never Walk Alone' - the anthem of United's arch-rivals Liverpool.
It's unclear where the footage was recorded, although footage of Feyenoord supporters had earlier been uploaded from Manchester's popular Walkabout bar.
Feyenoord are no strangers to Manchester, having visited United last year for a Europa League match at Old Trafford - when they also took the chance to wind up Reds fans, chanting City's beloved 'Blue Moon' song. Why they're so desperate to troll United, we're not quite sure, but they've certainly got all the songs in their repertoire.
This year Feyenoord head to City having lost all four of their games in the Champions League, including a 4-0 thrashing by Pep Guardiola's team in the opening round of fixtures.
Although they have no chance of qualifying for the knockout stage, the event is viewed as a huge event in Rotterdam as Feyenoord hardly ever qualify for Europe's Premier club competition.
Feyenoord are known for having a major hooligan element, and Greater Manchester Police have decided to give the club a police escort to City's stadium for tonight's match.
