Maarten Stekelenburg plays his football in Italy for club side Roma. In his first season in Rome he has been a big success and is the first dutchman to play for the club. It is a big tournament for Stekelenburg as he tries to fill the gloves of his predecessor Edwin Van Der Sar. Stekelenburg is product of the Ajax youth system, where he followed in Van Der Sar's footsteps.
Rui Patricio plays his football back in his native Portugal for Sporting Lisbon. Euro 2012 will be his first international tournament and will no doubt want to impress having fairly recently broken into the national set up.
Hugo Lloris plays in France for Olympique Lyonnais, and remains number one for both club and country. He heads into the tournament as a relative novice in international tournaments. So this could be his time to shine.
Manuel Neuer plays for Bayern Munich, despite being linked with other top sides from around the continent. He has now stamped his authority on the German keeper jersey and is set to keep goal during the championships.
Spain's Iker Casillas has amassed over 130 appearances for his country. His experience will be vital if they are to retain their European crown.
Danish goalkeeper Stephan Andersen who plays for french team Evian in Ligue 1. He is the long-term replacement for Thomas Sorensen as long as he manages to impress during Euro 2012.
Wojciech Szczesny has remarkable composure, agility, and command of his area which led to his establishment as Arsenal's first choice at just 20 years of age. He has gone under the radar at Arsenal this season, which is a good thing comparably to the mistakes made by his predecessors and highlighted by the media. Poland will be hoping he can maintain his solid form and keep the back four tight if they are to have any chance in the tournament.
Shay Given will be relishing the opportunity to go toe-to-toe with some of the top players from a round the world. In the Premier League he has proved himself to be one the best the league has ever seen. Lack of trophies and a disappointing qualification record with Ireland will be Given's biggest gripes when he eventually hangs up his boots. He will be hoping here that they can give him something to remember by getting into the knockout stages and beyond.
Petr Cech has been a mainstay in a Chelsea side that has collected trophies over the past few years. His performances in the Champions League this season have drawn praise from all quarters, especially the outstanding display at the Nou Camp to progress to the final. Playing for the Czech Republic is a different kettle of fish and in recent years the Czechs have failed to make much headway in major tournaments at all. Cech will be hoping he can bring the needed experience to progress for the group stages at the very least.
England goalkeeper Joe Hart has been a consistent performer in the Premier League for Manchester City and also when he has had the chance to represent his country. England had struggled for years to replace David Seaman, but they have now discovered a genuine world class keeper in Joe Hart. Hart was part of the Manchester City team to lift the Premier League title this season in an extraordinary finish to the season. He will be hoping he can re-create this form for England at Euro 2012.
