Switzerland coach Koebi Kuhn has urged his players not to dwell on the loss of captain Alexander Frei.

The country's all-time leading goalscorer, with 35 goals in 59 appearances, has been ruled out of the remainder of Euro 2008 due to injury.

Frei limped out of the Switzerland's 1-0 curtain-raising defeat to Czech Republic on Saturday after a collision with Czech defender Zdenek Grygera.

"Of course it hurts for us to lose our captain and one of our most important players, our goal-getter," Kuhn said.

"But I have already told the team that the looking back is over. It doesn't help us to look back. We have to look ahead to our next match which we will just have to win without Alex."
