Tottenham boss Harry Redknapp believes Portsmouth want "in excess of £20million" for England striker Jermain Defoe.
Defoe wants to leave Fratton Park but Spurs chairman Daniel Levy could not agree a fee with Pompey chairman Peter Storrie when the pair met on Friday.
Redknapp, when asked how much Pompey would want, said: "I think it's in excess of £20million probably. The two clubs are miles apart in their valuation of the player so I think we'll have to move on."
Pompey manager Tony Adams insists he will have the final say over whether Defoe leaves the club.
Defoe may miss Saturday's FA Cup visit of Bristol City as he was absent from training after phoning in sick and Adams revealed the club sent a doctor to the striker's Hertfordshire home to assess his condition.
Adams said: "Peter Storrie had a meeting with him last Wednesday, which I sat in on, and Jermain expressed a desire to leave.
"I think Peter is talking to a few clubs about him but the final decision will be mine and I have a price in mind of what I think he is worth.
"He is a superb player and a great goalscorer but I have not yet made up my mind whether or not I am going to sell him.
"I have to make a call on that like I had to with Lassana Diarra when Real Madrid came knocking.
"If I wanted to play him against Bristol City I could because he is still a Portsmouth player but it looks as if his illness has taken that out of my hands."
