Harry's Kewell agent has confirmed the names of five of the six clubs interested in signing the Leeds forward.
AC Milan, Barcelona, Liverpool, Arsenal and Manchester United plus an unnamed side are all chasing Kewell, who is unsettled at Elland Road, where he has a year left on his contract.
Bernie Mandic also revealed the Australia international has a clause in his contract that guarantees his availability to play for his country.
"The British press had him signed, sealed and delivered to Manchester United three weeks ago, then it was Arsenal, then Liverpool, but for the moment he remains a Leeds player," Mandic said.
Australia's international future is unclear after FIFA's executive committee voted against awarding an automatic World Cup place to the Oceania confederation.
However, Mandic insists that has not changed Kewell's determination to play for his country whenever he can.
"While FIFA have yet to decide whether the winner of the Oceania group plays-off in South America or goes via the Asian route, he has a clause in his contract and any future deals that makes him automatically available to play for the Socceroos at the behest of the national coach," said Mandic.
