Guangzhou Evergrande, a Chinese Super League club, is currently building the world's largest football-only stadium, with a seating capacity of 100,000 and 168 VIP boxes. The stadium is expected to be completed in 2022.
Evergrande Chairman Hui Ka-yan was involved in the design process, which is a significant undertaking for the club.
However, not all ambitious stadium designs have come to fruition. In 2010, a local business consortium proposed a 'Siamese-style' stadium for Liverpool and Everton, with the two grounds side by side and connected by a central 'spine'.
Although the idea was intriguing, Liverpool ultimately decided to expand their current stadium, while Everton is planning a 52,000-capacity waterfront stadium.
Another notable example is Chelsea's bid to buy Battersea Power Station in 2012 and redevelop it into a 60,000-capacity stadium. Although the plan was ambitious, the club ultimately lost the bid.
Barcelona, on the other hand, considered building a new stadium off the bay of the city, connected by a bridge. However, they ultimately decided to increase the capacity of their iconic home, the Nou Camp, to 105,000 by the 2021-22 season.
