Kewell has treatment in Australia

Kewell has been unable to find answers in Europe

Liverpool's Australian winger Harry Kewell has returned to Sydney for treatment on groin and foot injuries.

He has failed to find the answer in Europe to the groin problem that has sidelined him since the World Cup and the arthritic condition in his foot.

The 27-year-old said: "I'm over here trying to sort out my injuries, we have tried everywhere in Europe.

"We have got to a point where we are trying Australia because it has got the best surgeons in the world."

Kewell hopes to have a prognosis on the injuries that have plagued him for the best part of two seasons by Friday.

But he revealed he was unclear when he would return to action for Liverpool.

Kewell missed Australia's World Cup second round defeat to eventual World Champions Italy with what was initially thought to be gout but that was later discovered to be an incorrect diagnosis.

He aggravated his groin problem in last season's FA Cup final against West Ham and the then Socceroos coach, Guus Hiddink, admitted Kewell was not fully fit for the group stages of the World Cup.
