Harry Kewell hit back at Leeds United, saying he had no choice but to leave the English Premier League club after it failed to offer him a new contract.

Kewell's move to Liverpool has been marred by implications from Leeds that he pocketed STG2 million ($A5 million) from the deal while his agent Bernie Mandic admitted his company was paid STG2 million out of the STG5 million ($A12.5 million) transfer fee.

Kewell and Mandic both denied the Australian midfielder received any money from the transfer but said Leeds had lied by claiming it had offered him a new contract.

"I'm sorry to say Leeds never offered me a contract and put figures down in front of me," Kewell said at a press conference at Anfield.

"It's sad in a way because after nine years you expect to build a friendship with the club and there was no friendship there."

Kewell had one year left on his contract at Leeds and the club claimed he and Mandic had threatened to see the final season out and then leave for free under the Bosman rule.

But Mandic said without an offer to extend the deal and with Leeds negotiating with other clubs to sell Kewell since last December, he was forced out of Elland Road.

Kewell hoped the Leeds supporters understood his situation and bore no grudges.

"I've always said Leeds have been perfect for me," he said.

"For nine years they've supported me, I've got nothing against the fans and I hope they've got nothing against me."
