Details of the Argentina superstar's €555m deal were published in the Spanish press and the former president says he played no part in the controversy
Josep Maria Bartomeu has denied leaking Lionel Messi’s Barcelona contract to the media.
There was a furore on Sunday when Spanish newspaper El Mundo ran leaked documents detailing the contract of the world’s best player.
The details of the contract revealed that Messi picks up fixed incomes and bonus payments which amount to €138m (£112m/$167m) in annual earnings.
Barcelona were quick to express their fury, and said legal proceedings would be taken.
