Hours before his team take on Barcelona in Spain for their Champions League semi-final second leg, Hoeness said the club had nothing to do with the account under investigation, which was used only for "stock market gambling" and financed by the late Robert-Louis Dreyfus, a former head of sports manufacturer Adidas.
"From 2002 to 2006 I was really gambling [with stocks]," Hoeness told Zeit newspaper. "I sometimes traded day and night with sums that are now difficult to comprehend. Some of those amounts were extreme.
"This gave me a kick, pure adrenaline," said Hoeness, who has been under mounting pressure to step down.
"My life changed on March 20 at seven in the morning. I stood there in a bathrobe and the prosecutor was at the door. That is when hell started for me.
"I made a huge mistake which I want to try and correct as much as possible," said the outspoken Hoeness, who could face a jail sentence depending on the amounts in question.
"I feel I have been catapulted to the other side of society. I made a mess of it but I am not a bad person."
"He said 'let's do something together', he would finance it," Hoeness said.
"That is how the millions came on to the account. It was always clear it was an account for [stock market] gambling. This account was only Uli Hoeness."
"I am also now older. I am 61," Hoeness said.
