Australia coach Holger Osieck dismissed talk surrounding Harry Kewell's international future and insisted all his focus was on securing the point the Socceroos need to ensure progress in their 2014 FIFA World Cup Brazil™ qualification programme when they meet Thailand tomorrow.

Kewell was withdrawn shortly after half-time in Australia's 1-0 defeat to Oman in Muscat on Friday and has left the squad to return home for treatment with new club Melbourne Victory.

The former Liverpool and Galatasaray winger cut a dejected figure when he was taken off, prompting talk of a rift with Osieck, but the German is adamant that is not the case, nor his primary concern.

''He's got a muscle strain, so in consultation with the medical group we decided to give him the opportunity to go home to get individual treatment, that's the background,'' Osieck said.

''I'm not a doctor, but according to our medical people it was serious enough to not make him available for this game."

When asked about Kewell's long-term future, Osieck added to the Sydney Morning Herald: "We are focusing on our game on Tuesday, I'm not talking about his career.

"Harry is still a good player. He is still one of the top players in Australia, so that is a question at the wrong moment. He definitely figures in my plans.''

Australia had to come from behind to edge the Thais in Brisbane in September and Osieck accepts it will be a tough Group D clash in Bangkok.
