Greece coach Otto Rehhagel has called for total commitment from his players ahead of the potentially decisive World Cup qualifier against Denmark on Saturday.
The European champions need to win in Copenhagen on Saturday and beat Georgia four days later to make certain they finish second in Group Two and qualify for a play-off spot.
“The importance of this game is known to us all and only a win will do,” Rehhagel said.
“Every player in my team must exceed his own capabilities in front of a sell-out crowd in what must be an exceptional game.”
With Ukraine already qualified as group winners, Turkey, Greece and Denmark are locked in a three-way fight for the runners-up spot.
Turkey are currently second with 20 points and one game left to play, while third-placed Greece, on 18 points, and fourth-placed Denmark, on 16 points, have two matches left.
“Getting closer to the peak of the mountain, it always gets tougher and we must show we can climb the last few metres,” said Rehhagel. “I hope that on Saturday we will be ready to show our class.”
Rehhagel is likely to be without three key players with defenders Traianos Dellas and Takis Fyssas recovering from injury and striker Angelos Haristeas suffering from a head wound.
“Whoever plays, what I want from my players is pre-game fever,” he said.
“I want them to feel a bit nervous going into the match because if you want to achieve great things in such competitions you must have that fever and then come up with a special performance on the pitch.”
