Polish striker Pawel Kryszalowicz has insisted that he will be fully fit for the team's opening game against hosts South Korea on 4 June.
Expected to partner Emmanuel Olisadebe in attack, Kryszalowicz's fitness levels dipped as his club Eintracht Frankfurt chopped and changed coaches during the season and suffered financial problems.
"Everyone will see whether I'm in shape on 4 June," said Kryszalowicz, who did admit that he was still recovering from jet lag.
"And some - especially the host - may be surprised."
"I was a bit tired at the end of the season. The changes of coaches in Eintracht also weren't good for me.
