Potential Chelsea buyers have been hit by a list of demands they must meet before making any formal offer.

The Daily Mail says the parties interested in bidding for Chelsea have been advised to submit a detailed background report on all investors amid the growing anxieties over appropriate club ownership.

Those intent on making offers ahead of Friday's bid deadline are also being asked to file comprehensive details of their motives for the club moving forward.

Sources close to the sale say there are as many as 200 interested parties. As it stands, property developer Nick Candy, a consortium led by LA Dodgers part-owner Todd Boehly and a group led by British businessman Sir Martin Broughton are among those rated as the most serious contenders.

On Monday, news of a £2.7billion offer from Saudi Media Group emerged.

New York-based merchant bank Raine are advising Chelsea on the sale, while Sportsmail understands Blues director Marina Granovskaia is also offering interested groups guidance during the process.

Potential bidders have been provided a checklist of items to submit with their offers, which parties are being advised should be made to Raine, the Premier League and the Government.

Bidders will be asked to supply a proof of funds letter, a full list of advisers, a business plan and a timescale for completion to accompany offers.

But potential buyers are also being asked to provide their motivations behind the offer and a detailed report on the background of all the investors.

Buyers are also advised that a cash offer - and being the highest bidder - will be crucial, however other well-placed sources insist that any consortium or individual's ability to preserve employment at all levels and fulfilling the club's existing financial obligations will also be a key factor when deciding which bid is successful.
