Pantelis Kapetanos insists Greece will not be afraid to take on Lionel Messi and Argentina in their final World Cup group game.
The Greeks must match Group B rivals South Korea's result against the pointless Nigeria on Tuesday to progress to the knockout stages of the South Africa finals.
Realistically, it means Otto Rehhagel's side have to conquer the Albiceleste, who have six points from their first two games, but Kapetanos is remaining upbeat that Greece will not be overawed by Diego Maradona's outfit.
"We all know Argentina and know how good they are," said the 27-year-old, who plies his trade for Steaua Bucharest.
"They have 22 fantastic players and Messi, who is one step higher in quality - the best player in the world.
"All the Argentina players are exceptional, but it's also up to us.
"If we play well, we can make it. If we stay concentrated for the entire 90 minutes, I believe the match can be won.
"We just have to play the way we know."
