How they qualified: Had a strong campaign but even then 25 points was only enough for second place in their group behind Bosnia-Herzegovina, meaning a hard-fought play-off victory over Romania was their route to the finals.
World Cup pedigree: Undistinguished. The Euro 2004 champions have only ever won one World Cup finals match: a 2-1 win over Nigeria in 2010. Their only other finals appearance came in 1994, when they failed to score a single goal and lost every game. The only way is up.
Main man: Kostas Mitroglou. The tricky Olympiacos striker has scored a few stunners in the Champions League this season and has been linked with a move to Liverpool in the summer.
One to watch: Panagiotis Kone: The 26 year-old attacking midfielder captains Bologna and was one of few players to emerge with much credit as the Italian side were relegated from Serie A in May 2014. He missed Euro 2012 after being sent off in a friendly, and will be eager to make up for it this time around.
What are their chances? Reaching the knockout stages would be a triumph but then Group C is rather lightweight. They conceded just four goals in ten games during qualifying and their sturdy back-line could see them grind a way through to the Round of 16.
