There was a group of 3 rag fans (possibly Irish) next but one to my wife and me in East Stand L3, revealed as such when (like the subject of the original post) one of them jumped up to celebrate the Utd goal. Happily no violence ensued but the guy directly in front of them gave them a ‘strong talking to’, after which they kept completely quiet. When we all started doing the Poznan following Haaland’s goal they were ‘persuaded’ to join in: seeing three rags participating in the Poznan in celebration of City’s win seemed to me to be just punishment for their infiltration of a home supporters section!
