A video emerged on social media on Tuesday which appeared to show City players and staff singing a distasteful version of Liverpool's 'Allez, Allez, Allez' song as they traveled on a plane following Sunday's victory at Brighton which clinched the title, Sky Sports reported.
The song, which City fans had changed the lyrics to, makes reference to Liverpool fans ‘crying in the stands’ and being ‘battered on the streets’ at last year's Champions League final in Kiev, which Liverpool lost 3-1 to Real Madrid. It also contains the lyric ‘victims of it all’.
Liverpool fan Cox was attacked by Roma supporters ahead of the Champions League semifinal at Anfield.
A Manchester City statement insisted the song in question has been a regular chant during the 2018-19 season and refers to the 2018 UEFA Champions League final in Kiev.
"Any suggestion that the lyrics relate to Sean Cox or the Hillsborough tragedy is entirely without foundation," the statement added.
Reports also suggested the song referred to City captain Vincent Kompany injuring Mohamed Salah earlier in the season.
Liverpool has chosen not to comment on the video.
City's win over Brighton ensured it retained the title by a point from second-placed Liverpool.
