Stadium plans are seen as key to the selection process, with four bidders shortlisted by US bank Raine Group.
Boehly has teamed up with real estate developer Jonathan Goldstein, who brings his expertise in this area to its proposal.
They are already talking to the former director of the abandoned Roman Abramovich redevelopment project, David Hickey. Architect Janet Marie Smith was also consulted.
She has worked on a slew of stadium renovations in America, including Oriole Park, Atlanta’s Olympic Stadium, Boston Red Sox’s Fenway Park and over £200million worth of upgrades at Dodger Stadium in Los Angeles. Angeles.
Although planning permission for Chelsea’s proposed 60,000-seater stadium expires two years ago, Hickey only left as project manager in December, meaning he has the latest knowledge on this project.
His other major work in London includes Arsenal’s Emirates Stadium and leading the infrastructure for the 2012 Olympic Park venues.
Boehly, the Ricketts family, Sir Martin Broughton and Stephen Pagliuca are all fine-tuning their offers for Chelsea ahead of the April 11 deadline for final offers.
All have been asked to commit additional funding of £1 billion, which includes the development of the bridge.
The Ricketts have experience rebuilding the Chicago Cubs’ Wrigley Field, which cost up to £760m.
They also have the financial might of US hedge fund manager Ken Griffin behind them. He is worth around £20 billion.
The additional funding requested by Raine is also expected to cover investment in the first team to keep Chelsea competing at the highest level in Europe and other developments around the club.
Raine hopes to submit a preferred offer to the Treasury by April 18.
