Todd Boehly's consortium is already in discussions over redeveloping Chelsea's Stamford Bridge stadium should they complete a takeover of the club.
A lengthy list of bidders has been narrowed down to a shortlist of four by the merchant bank managing the transaction, the Raine Group. Boehly's consortium, the Ricketts family, Sir Martin Broughton and Stephen Pagliuca are those who have made the cut.
Plans for the development of Stamford Bridge are believed to be high on the list of requirements for a successful candidate, with the stadium in need of modernisation and expansion.
British property tycoon Jonathan Goldstein is part of Boehly's consortium, and according to the Evening Standard they are already in discussions with the former project director of the previously abandoned renovation of the ground, David Hickey.
Hickey only left his role in December despite the planning application expiring two years ago, so he still has an intimate knowledge of what will be required for the scheme.
Architect Janet Marie Smith, who is something of a specialist having redeveloped a number of stadia in the United States, has also been contacted.
Boehly's consortium were thought to be the frontrunners, but they may now face an uphill battle with Chicago Cubs owners the Ricketts family - backed by hedge fund manager Ken Griffin - reported to be the Raine Group's preferred candidate at this stage.
The theory is that the Ricketts' prior experience in top-level sport and readiness to step into Roman Abramovich's shoes at Chelsea has put them at the head of the queue.
The deadline for improved bids is 11 April, with Raine hoping to submit a preferred bid to the UK government on a week later.
