Harry Redknapp said "there is nothing on me in this world" as he told Premier League bung investigators he was "sick and tired" of slurs on his name, a court heard on Wednesday.
The Tottenham manager "voluntarily" revealed details about his Monaco bank account during interviews with the Quest inquiry in 2006, top accountant Nigel Layton said.
Redknapp told Layton "I don't care who looks" as Portsmouth were looked into by the investigation led by former Metropolitan Police commissioner Lord Stevens.
It is alleged Redknapp said: "A friend said to me, he said 'Harry, I can't believe it's always you, I have dealt with you enough times. Your problem is your name, Harry, and you have got a Cockney accent'.
"People don't know me and I am sick and tired of it.
"There ain't nobody who is more of a fan... My son has been a top footballer.
"If there is any mud to be thrown, I seem to get on the end of it for whatever reason."
Southwark Crown Court heard transcripts of a conversation which took place between Layton - managing director of Quest - and Redknapp in November 2006.
Redknapp added: "I don't care who looks, your people can look. Nobody will ever find anything on me. I don't care who looks or how hard because there is nothing on me in this world."
Layton and other officials from Quest met Redknapp several times after first talking to Portsmouth executives, including Milan Mandaric and then-chief executive Peter Storrie, in May 2006.
Under cross-examination by Redknapp's lawyer John Kelsey-Fry QC, the financial executive said the manager was "forthcoming" in telling the inquiry about his Monaco account.
"Quest had no power whatsoever to order the disclosure. All we could do was ask for the disclosure," Mr Layton said.
"In this instance, voluntary disclosure was forthcoming."
Redknapp, 64, and Mandaric, 73, deny two counts of cheating the public revenue.
