Tottenham boss Harry Redknapp insists he doesn't know the details of Demba Ba's buyout clause in his Newcastle United contract.
Redknapp last week increased speculation about the Senegal international after claiming there is a buyout clause, reported to be £7million, within the striker's contract.
And the Tottenham boss has again indicated he is paying attention to Ba, adding: "I keep hearing conflicting stories about the buyout clause.
"One person says one thing and (then) somebody comes on and says he can be bought out for X amount.
"I think the only people that probably know are Newcastle and Demba Ba."
