Unflattering comments about Kewell and Socceroo disharmony at the recent World Cup were last week publicly aired by Fox Sports FC panelist Robbie Slater  in a column.

He wrote: “No player will say it publicly but there was disharmony. And here's one story to put a new spin on the spin. It's an incident involving Harry and another player, whose privacy I will respect.

“It happened at Australia's farewell dinner after the Socceroos' exit in South Africa. Put simply, the player told Harry to f... off, saying he was of no value to the Socceroos any more.”

Slater also questioned Kewell’s future effectiveness as a national team player while also praising his contribution to the green and gold.

He added: "While Harry has been a wonderful player for a very long time, I believe that there's little point selecting him for future Australia teams.

"He's approaching 32 and has had a long history of injuries. At that age, it's surely not about to get better.

"So one of the first jobs for the man who takes over as Socceroos coach is to make the call. It has to be made. Until now, no one has been brave enough to tell Harry his time is up.

Slater added: "We need to find a striker who is younger and fitter - and start working on him now.

"Yes, on his day Harry was very special and could change a game but I just don't think he ever fulfilled his potential. It all comes back to that long list of injuries."

Tonight the Galatasaray star will have his say on those assertions in what is tipped to be must-see TV.
