Sadiq Khan has warned Chelsea that Stamford Bridge is too small and suggested the Blues may be looking at their London rivals with envy due to their larger grounds.

However, the Mayor of London has expressed a willingness to hold discussions with the club about the possibility of constructing a new stadium.

Chelsea’s ownership group appears split between renovating Stamford Bridge or relocating to a new site at Earl’s Court, a move that would involve collaboration with the mayor’s office.

Currently, Stamford Bridge ranks as the 10th-largest stadium in English club football with a capacity of 40,343—smaller than even Championship club Sunderland’s ground.

While Stamford Bridge has hosted numerous memorable moments, its size significantly lags behind the stadiums of London rivals West Ham, Tottenham, and Arsenal by approximately 20,000 seats.

“My message to Chelsea is come and speak to us in relation to what you want to do,” Khan told The Times.

“Chelsea are the victims of their success, and Stamford Bridge is now too small for them. After all, this is a team that has twice won the Champions League.

“We work closely with all seven of our Premier League clubs but I’m sure Chelsea look with some envy at the stadiums some of their rivals in London have.

“We’re really keen to make sure that Chelsea, as we are with all our clubs, continue to flourish and thrive, so we’re open to talking to Chelsea about what plans they have.

“At the moment they’ve not approached us. But we’re here.”
