A court in England has heard that Liverpool's captain Steven Gerrard "lost his self control" and hit a businessman in a bar row over background music.
Gerrard's six co-defendants earlier pleaded guilty to being involved in the bar brawl on December 29 leaving the 29-year-old England midfielder to stand trial.
Prosecutor David Turner QC told a Liverpool court 34-year-old Marcus McGee, in charge of music for the night at Southport's Lounge Bar, refused to let Gerrard take control of a CD player.
Security camera footage showed Gerrard talking to McGee before one of the co-defendants elbowed the businessman.
Turner said Gerrard quickly joined in with a "succession of well aimed uppercut punches delivered with the style and speed of a professional boxer rather than a professional footballer".
The England international pleaded not guilty to a charge of affray, claiming he was acting in self-defence.
