Manchester City fans appear to have been filmed causing significant damage to toilets at Old Trafford after Wednesday night’s derby in the EFL Cup.

A video posted online showed supporters kicking urinals and sinks from the wall after United’s 1-0 victory. They can be heard chanting “City, City, City” in the video, which was posted on Twitter by the @footyawayday account.

“Man City fans smashing up the toilets at Old Trafford last night,” read the accompanying message.

The two sets of supporters clashed in the streets after City’s win in the Premier League match in September. Pep Guardiola’s side saw their winless run extended to six matches after Juan Mata’s goal booked United’s place in the next round.

The incident occurred on the same night as West Ham United and Chelsea supporters clashed at the London Stadium. The FA has launched an investigation after fans were seen attempting to break through segregation, with allegations that coins were thrown from the home end.
