Three US consortia are interested in buying Chelsea amid sanctions imposed on owner Roman Abramovich.
The Russian billionaire can still sell the "blues", although his assets are frozen, as "the application for a license to sell the club will be considered" by the British government.
Abramovich will not see the money, instead he will have to hand over the whole process to the government, which will then determine where the money will go.
According to the Telegraph, the New York-based investment bank Rhine, which deals with potential sales, has received nearly 150 inquiries, but so far three have emerged as the most serious, all from the United States.
Todd Boelli, along with Hansorg Vis and another businessman, made an official offer of between 2 billion and 2.5 billion pounds.
The other two proposals are from the Rickets family, which owns the Chicago Cubs, and New York Jets owner Woody Johnson.
The Ricketts and Johnson have not yet responded to allegations linking them to Chelsea, but both sides are believed to have made serious proposals to acquire the London club.
If the reigning European champions do not find a new owner, then Chelsea are facing the possibility of a financial armageddon, which will include a state of failure and slow disintegration.
It is assumed that Chelsea will not be able to work in its current state for much more than two months before the financial impact becomes serious.
