Sources at Manchester City suggested that Joorabchian and Pini Zahavi had developed links to the club under the regime of the previous owner, Thaksin Shinawatra, who had originally appointed the City chief executive Garry Cook. Cook himself said that the club "did not need and did not seek" Joorabchian's help in facilitating the negotiations with A.C. Milan.[2] Joorabchian was involved in the leaking of Carlos Tevez's transfer request to Manchester City on 11th December 2010, by revealing the news to the newspaper, News of the World.
