The Euro 2004 winner feels that the Ethniki's status as underdogs could prove to be an advantage in the quarter-finals match versus the Nationalelf
The Greece legend feels that the pressure to progress is solely on the Germans as the Ethniki head into the clash as major underdogs.
"I believe that since we are not the favorites to win, the German team will be under more pressure than us," Nikopolidis was quoted as saying on the official UEFA website.
"We got this far by doing our best as a team, and I believe that from now on we have nothing to lose. We are playing against a favorite this time and they may win the tournament because they are a very good team.
"Our basic advantages are our good defence and that we can counterattack quickly. We will focus on that and hope that everything will be OK.
"If we can keep Germany outside our penalty area for a long time, then at the end of the match we will have more chances to score and win."
Friday's match in Gdansk kicks off at 2:45 p.m. ET.
