Galatasaray winger Harry Kewell was fully fit for Australia's World Cup opener against Germany, tribalfootball.com has learned.

A source deep inside the Australia camp has told tribalfootball.com that Kewell is convinced he is in 100 per cent top shape and could have started Sunday night's dismal defeat to Germany.

Australia's medical chiefs have also given the former Leeds United and Liverpool star the all clear.

For Kewell's part, he is convinced he has 90 minutes in his legs and can start against Ghana this weekend.
