Group A is very much for the taking, as there is no clear favorite—which may help the co-hosts advance. For what it's worth, the co-hosts are the lowest-ranked FIFA-ranked team in the tournament. But neither Greece, Russia or the Czech Republic should scare Franciszek Smuda's squad, and the Poles can rely on Borussia Dortmund striker Robert Lewandowski, whose 22 goals in the league sparked Dortmund to a Bundesliga title.
In addition, his clubmate Lukasz Piszczek and Arsenal goalkeeper Wojciech Szczęsny will anchor the back. If Poland beats Greece, that should be the spark the co-hosts need to reach the second round.
As for the 2004 champions, they're an unspectacular side that went 17 matches without a defeat (and undefeated in qualifying) after Fernando Santos took over the side just after the 2010 World Cup. But they have struggled in friendlies and with the exception of Theofanis Gekas, they lack goalscoring threats. But who knows? There'll probably be one team that will shock people at Euro 2012, and maybe the Greeks will make another 2004-like run.
