Euro 2012 Standings: Teams Who Must Rebound Quickly from Slow Starts

While some teams have started beautifully at Euro 2012, others will be scrambling to save their tournament hopes in their second match of the group stage.

Twelve teams have taken the pitch thus far, combining for 15 goals in six matches.

Russia, Denmark, Germany and Croatia have all gained three points in their respective groups, but some of Europe's finest squads haven't been as fortunate.

Here are the teams that must rebound immediately or risk being bounced from the tournament.

Czech Republic

There's no shame in falling to the group favorites, but the Czech Republic's 4-1 defeat to Russia is highly concerning.

They lacked creativity in their offense, Milan Baros and Tomas Rosicky looked old on the attack and the Czechs let young midfielder Alan Dzagoev make an absolute mockery of their defense. Yes, they have world-class keeper Petr Cech between the posts, but he can't make saves if his defense doesn't challenge opposing attackers.

With Poland and Greece playing to a 1-1 draw, second place in Group A is still up for grabs. The Czechs desperately need to snatch three points Tuesday against Greece, or they will face an uphill battle heading into their critical match with Poland.

Netherlands

In the most shocking upset thus far, the Netherlands fell to Denmark 1-0 on Saturday.

Despite being the better side for most of the match and creating a host of chances, the Netherlands' world-class goal scorers couldn't find the net.

Arsenal striker Robin van Persie was unsuccessful on all seven of his shot attempts, with four of them missing the target completely. He also ruined a perfect chance to equalize before halftime, botching a gorgeous pass from Wesley Sneijder.

His elite teammate in the midfield, Arjen Robben, wasn't overly impressive, either. Robben also missed on seven shots, and he ruined a gift of a goal from Denmark keeper Stephan Andersen.

If the Netherlands doesn't get at least one point against Germany on Wednesday, they could be eliminated before the knockout rounds. For the second-place finisher at the 2010 World Cup, this would be a humiliating result.

Portugal

The Portuguese had their chances against Germany, but they were simply the lesser squad.

Cristiano Ronaldo made a few brilliant plays, but he was unable to find the net. And with virtually no help from his supporting cast, he couldn't lead Portugal to an upset victory over the "Group of Death" favorites.

Portugal will have a critical match against the Netherlands next Sunday, but first they must take care of business against a surprising Denmark side.

The Danes proved in their first game that they can't be taken lightly. Still, I think the individual brilliance of Ronaldo and Nani will earn Portugal the win.

The Portuguese are desperate for three points, and if they don't obtain them here, they will put enormous pressure on themselves against the Netherlands.
