It had been incorrectly suggested the £1m Tottenham were owed was some kind of sell-on clause, but Spurs have insisted they came to the arrangement with Portsmouth to try to help the debt-ridden club, and the say they are justified in their debt demand.
"The transfer of Younes Kaboul was completed and Portsmouth pressed for an immediate payment in order to alleviate their cashflow situation," said the Tottenham statement.
"We were assured that the transfer of Begovic would be completed before the end of the transfer window.
"Our intention had been to assist a fellow club in financial difficulties whilst at the same time protecting our commercial position.
"We shall continue to do the latter and trust that this statement clarifies the position."
