Manchester City have confirmed their City of Manchester Stadium will be renamed the Etihad Stadium with immediate effect with chief executive Garry Cook branding the deal as ''one of the most important arrangements in the history of world football''.
City have agreed a 10-year partnership agreement with Etihad Airways that will "significantly expand the existing commercial relationship" between the pair.
Etihad Airways already sponsor the club's shirts, and that deal has been extended as part of the agreement.
''We are delighted to announce a 10-year extension of our partnership with Etihad Airways,'' said Cook. ''The partnership will not only cover a shirt sponsorship extension, but also the Etihad Stadium. The wider area around the stadium will be known as the Etihad Campus. There are other elements, such as media, business and community co-operation.
''It could be one of the most important arrangements in the history of world football.
''The partnership is about continuing to increase our investment in youth development, the scale and scope of our community programmes and continue to build our profile in major markets.
''The backdrop is UEFA's Financial Fair Play and this helps to make significant progress in that area. This is not just a wide-ranging agreement. It is a long-term commitment.''
A statement on the club's official website read: "The City of Manchester Stadium will be renamed the Etihad Stadium effective immediately, forming the centre piece of a newly-named Etihad Campus, which encompasses a large part of the Sportcity site in East Manchester, the popular City Square entertainment space and additional existing and planned facilities."
