Wayne Rooney's agent was left in tears after being threatened over the player's contract, a court has heard.
Rooney's agent was told to pay Mr Hyland a cut of his earnings
John Hyland and brothers Christopher and Anthony Bacon all deny charges of blackmail at Warrington Crown Court.
The jury heard the men burst in when Rooney's agent Paul Stretford was talking to former agent Peter McIntosh.
Mr Hyland shouted at Mr Stretford to make him sign a contract which would have forced him to pay a percentage of Rooney's earnings, the court was told.
The alleged threat happened at a meeting between the two agents in a Cheshire hotel room in June 2003, which Mr Stretford had secretly filmed and taped.
Prosecutor John Hedgecoe told the court: "Mr Hyland was grossly aggressive and intimidating.
"He demanded that Mr Stretford sign the contract that was on the table.
"He shouted and repeatedly banged his fist on the table.
"Anthony Bacon stood to one side of Mr Stretford but Christopher Bacon leaned over Mr Stretford as he sat at the table, spoke menacingly to Mr Stretford and added
to the general atmosphere of intimidation.
"After a little over two minutes, the three men left the room. Mr Stretford was terrified.

"Mr Stretford left the hotel and telephoned his security consultant from his car, telling him what had transpired and he then burst into tears."
Mr Hedgecoe told the jury it was not clear who was to profit from the contract which Stretford was being urged to sign.
The case continues and is expected to last 10 days.
