Poland boss Franciszek Smuda has said that Euro 2012 Group A opponents Greece are 'perfect' in defence.
The co-hosts, who kick off the competition against 2004 winners Greece in Warszawa, will be eager to get off to a strong start. However, Smuda admits that a draw would be a good result.
"Their defence is great," he said. "They play perfectly in defence. Their defence is a big challenge for us.
"We would prefer to win. But it is an opening game, and a tie would mean we remain in the race, because then we would still have two games we can win."
The meeting will open the tournament this afternoon.
