Chelsea have doubled the projected cost of their new stadium to £1billion, which will make it the most expensive in Europe.
Roman Abramovich held talks with Chinese businessmen earlier this month about an investment of over £500million in their redevelopment of Stamford Bridge.
But the initial £500m cost, which was earmarked when the club received planning permission back in January, has been significantly hiked.
Antonio Conte's side will spend the next two-and-a-half years at their existing home before development begins in earnest.
Chelsea will then, however, face an extended four-year exile from the Bridge while works take place — most likely at Wembley, although they are still looking at as many as eight sites.
With those schedule changes, the Blues’ first game at their new ground has been pencilled in for the opening fixture of the 2024-25 season.
Demolition of the current stadium’s surroundings and building work on the adjacent railway line is planned to start next year.
