Vangelis Moras is touch-and-go regarding his participation in Greece's first game un the World Cup, according to team manager Takis Fyssas.

The Bologna defender has suffered a rupture and has a 50 percent chance of making the opener on Saturday against South Korea, Fyssas told the press on Sunday in South Africa after Greece's first training session in the hosting country of the tournament.

All other players trained without problems in Durban, with Moras following a special recovery program.

Manager Otto Rehhagel focused on tactics, as in the training camp at Bad Ragaz in Switzerland last week he has placed emphasis on the team's fitness.

"In Switzerland we worked a lot. This was obvious in the friendly games where players appeared quite tired," said Fyssas.

"Now the sessions will be shorter and more intensive, so that we can be ready on Saturday for our first game."
