The 35-year-old Nurnberg man is the all-time record goalscorer for the Czech Republic with 52 in 85 games.

And he believes the time is right to quit the international scene, with Czech coach Karel Bruckner also steppding down after this summer's Finals.

"I will retire after Euro 2008. I have been long decided, for two months now," Koller told Czech daily Dnes.

"I simply feel it is about time to end there. Also coach Karel Bruckner will leave the team and we have been bound up with each other. His decision (to retire) ended my hesitation.

"He is one of the best coaches I have worked with. I am sorry that I could not co-work with him in a club to be more in contact with him."

Koller is hoping to bow out by winning Euro 2008 as he believes there is a new generation of players coming through for the Czechs.

"It would be great to win it. But if we manage to advance from the group, I will not take Euro 2008 as a disappointment," added Koller

"My generation is being changed, young players are coming in. There is no Pavel Nedved, Karel Poborsky and, due to injury problems, no Vladimir Smicer either."

Koller says he plans to play on for Nurnberg next season before taking a decision on his future at the end of next season.

"I want to continue playing, to fulfil the contract at Nurnberg until the end of next season.

"And further? It is hard to say. It will depend on my health, on motivation and on the feeling if I still have the potential to play at such a level."
