While the competition will miss the likes of Croatia's Luka Modric and the Netherlands' Wesley Sneijder, there is still plenty of quality within the competition.
Each team will be looking to its star man to lead them to glory and Bleacher Report is here to rank them all.
Here's how the top eight players representing each quarterfinalist stack up.
With Giorgos Karagounis suspended for the next match, the next best thing for Greece is Kostas Katsouranis.
The defensive midfielder has featured in all three games for the Greeks so far, even playing as a center-back against the Czech Republic.
He was big part of Greece's Euro 2004 triumph and will hope to lead this new team to similar surprises through the remainder of the tournament.
Tomas Rosicky may still be an injury doubt for the game against Portugal, but until he has been entirely ruled out, he is the Czech Republic's main man.
Rosicky played well in the team's win over Greece in the group stages, and while his teammates did well without him against Poland, his play-making skills will be a necessity against Portugal.
It is hard to pick who is the most important player for France out of the trio of Samir Nasri, Franck Ribery and Karim Benzema.
For now, we'll go with the player who has played the best in the tournament so far.
Samir Nasri is the man where that is concerned, and he has been given the task as the team's main playmaker.
Italy look to none other than Andrea Pirlo as their star man. The influential midfielder has played his part for the team so far in this tournament.
It is the Juventus man who will be asked to unlock England's defense in the quarterfinal.
Bastian Schweinsteiger is Germany's main man. His all-round play in midfield is a big part of why Germany is so successful.
Schweinsteiger leads the team in assists at the moment. Mario Gomez scores the goals and Manuel Neuer stops them, but it is Schweinsteiger who Germany could not do without.
Wayne Rooney showed just how important he is for England by scoring the game-winning goal in his first appearance in the tournament.
If England continue to play well defensively, they may make it to the final with Wayne Rooney up top, leading the line.
He is the best forward left in the tournament.
Andres Iniesta edges out his extremely talented teammates with his mixture of vision, silky dribbling and exquisite passing. He can finish too, when he is ready.
The man who scored the winning goal for Spain in the World Cup will have to have a similar sort of impact for the Spanish to retain its European title.
Portugal may not have the best team, but they have the best player in the tournament. Cristiano Ronaldo's all-round attacking skills make him a threat to every team in this competition.
The fact that he may have found his scoring boots against the Netherlands might mean trouble for the remaining teams in the tournament.
