City have been criticised regarding a video that appears to show players and staff joining in a song that celebrates Liverpool supporters being “battered in the street”.
It is understood that the video was captured on a plane as the club’s travelling party returned from a 4-1 victory at Brighton on the final day of the Premier League.
That win saw City beat Liverpool to the title by a one point margin.
It is unclear which players and staff are involved in the singing.
In a statement, City described the song as a “regular chant during the 2018-19 season”, which recalls Liverpool’s loss to Real Madrid in last season’s Champions League final in Kiev.
It cites supporters being “battered in the streets” and “crying in the stands” and includes a line on Reds forward Mohamed Salah being injured, but with the actual culprit Sergio Ramos changed to Manchester City centre-back Vincent Kompany.
However, the vast majority of the party only join in at the “Allez, Allez, Allez” chorus.
“It’s honestly embarrassing that some Man City fans think it’s OK for their players to sing about fans being beat up,” one Liverpool supporter tweeted, while many others responded saying the video was “classless”, “unprofessional” or “naive”.
Manchester City also mentioned in their statement that “any suggestion that the lyrics relate to Sean Cox or the Hillsborough tragedy is entirely without foundation”.
Sean Cox suffered head injuries after being attacked by three Italian fans before Liverpool hosted Roma at Anfield in the Champions League in April 2018.
His brother Martin Cox told talkSport how “disgusted” he was by the video.
“Singing and chanting those words, it’s like it gives the impression that it’s OK for people to carry out attacks like that on people in the streets,” he said.
“It’s a matter very close to our hearts and whether they say it’s about Sean or not, the first thing I think about is Sean being attacked.”
Asked about Sean Cox’s condition, Martin Cox said: “He’s progressing, which is the most important thing. He’s still on a massive long road ahead, but he is progressing. Slowly but surely, he’s getting there. It’s baby steps at the moment but we’re on the right road.”
Martin Cox also made reference to a recent attack on a Manchester City fan in Germany:
“It wasn’t long ago that a Manchester City fan was attacked in Germany, so why they think it’s OK to sing songs about people being attacked on the streets when one of their own was attacked not long ago is very naïve,” he said.
“I think they’ve tarnished themselves now by coming out with songs like that because at the end of the day they are professional footballers and they’ve only let themselves down and their club down.”
The row comes just a few days after City broke their silence on the UEFA investigation that could the club being banned from European competition for one season.
