The report adds that if Chelsea wanted to stay put, they would have to demolish the stadium and start from scratch. Conversely, the Blues have been linked with building a new ground at the former Earls Court Exhibition Centre a mile away - but just buying the land would cost £500 million ($636m) before construction begins. And if owner Todd Boehly went ahead with a £60,000-seater stadium, it could cost upwards of £1 billion ($1.27bn).
