Euro 2012 co-hosts Poland will look to get their campaign off to a winning start on home soil as they take on surprise 2004 champions Greece at the National Stadium in Warsaw on Friday.
Poland are the lowest ranked team at the finals but they will still fancy their chances in group A which, on paper, appears an open contest.
Greece will enter the tournament in confident mood after an impressive qualifying campaign in which they saw off Croatia and Israel.
But they have not beaten Poland in five meetings since their European qualifying victory in 1987 in Athens.
Although they were surprise winners in 2004, in the last edition in Austria and Switzerland, they exited the competition without a point – an embarrassment they will seek to make amends for on Friday.
