In 2008, Sheikh Mansour bin Zayed Al Nahyan arrived in London with the aim of buying Chelsea Football Club, as he was admittedly a fan. However, the management at Chelsea declined his repeated advances. With his 10 day visa permit coming to an end, he ended up buying Manchester City Football Club instead. This became one of the most important takeovers in sporting history.
