England footballer Steven Gerrard launched a volley of uppercut punches at a man in a row over music, a court heard on Tuesday.
The millionaire star "totally lost it" and attacked Marcus McGee, 34, "with the style and speed of a professional boxer" in a bar brawl, it is alleged.
Gerrard was at the Lounge Inn in Southport, Merseyside on December 29 to celebrate Liverpool's 5-1 demolition of Newcastle United in the Barclays Premier League hours earlier.
The Reds' captain, who scored twice in the game, was enjoying a night out with a party of friends including Anfield legend Kenny Dalglish, 58, but trouble flared when Mr McGee refused to hand over a card controlling the CD player.
The victim was in charge of music for the venue after being given the card to pick songs for a staff party in an adjacent room to Gerrard's group.
David Turner QC, prosecuting, told Liverpool Crown Court Gerrard asked McGee for the card, saying: "Here y'are lad. Give me that lad."
Turner said: "Mr McGee took offence at his attitude and the expression 'lad' and he refused.
"Not many people on Merseyside, or indeed anywhere else, would refuse a request from Steven Gerrard but Mr McGee did. There can be no doubt that this refusal astounded Steven Gerrard."
Several minutes later CCTV showed Gerrard returning to the victim who was sitting alone at the bar and allegedly confronting him with abusive language.
McGee stood up and the pair were head to head, Turner said, "in the sort of hostile confrontation that is often seen between professional footballers".
