Tottenham and West Ham United must cough up £20 million if they win the right to buy the London Olympic stadium.
The London Evening Standard says the two competing clubs will have to pay a bond, thought to be £20million, if they buy the Olympic stadium.
The deposit, revealed by Sports minister Hugh Robertson, will ensure the winner does not back out of the move with Spurs' other option being a new ground at White Hart Lane.
Mr Robertson said the Olympic Park Legacy Company board will meet on 28 January to decide the future of the £500m state-owned stadium.
In a Lords debate last night he said: "I am absolutely sure that some form of deposit or bond will be taken from whichever preferred bidder emerges."
