Euro 2012 Results: Cristiano Ronaldo's Clutch Goal Will Be Portugal's Last Stand

Cristiano Ronaldo was able to earn Portugal a spot in the Euro 2012 semifinals with a tremendous late goal against Czech Republic. That's where the team's run will come to an end, however.

After another season with eye-popping numbers for Real Madrid, Ronaldo has carried his success over to the European Championships. He's scored three goals in four games and has looked like a man on a mission the entire time.

More importantly, his goals have come in key moments, when he's been known to struggle. He scored twice against Netherlands after Portugal fell behind 1-0, and then yesterday's header, which crushed all the confidence the Czechs had built up.

Scoring big goals like that will do wonders for Ronaldo, who has criticized for his lack of production for the national team despite gaudy club numbers.

The problem for Portugal won't be Ronaldo, but rather the team surrounding him. The Seleccao das Quinas lack depth, and that will be exposed by the winner of today's clash between Spain and France.

Beyond Ronaldo, Helder Postiga and Nani are the only two players Portugal can rely on to help create offense. While they are both solid contributors, neither of them can carry the team on his back if Ronaldo even has a slightly off night.

On the other hand, both Spain and France have plenty of offensive firepower, both in the lineup and coming off the bench if necessary. That type of balanced scoring is what it takes to survive a major tournament run.

Even with David Villa sidelined, La Roja are in good shape. They have a dominant midfield led by Xavi and Andres Iniesta. If Fernando Torres can continue to build off some recent success, he'll bring even more punch to the attack.

France has its fair share of star power, as well. Starting with Ronaldo's Real Madrid teammate Karim Benzema, who would love to outshine his fellow striker, Les Bleus are capable of making a run to the title match as well.

It all adds up to a semifinal loss for Portugal. Surviving the Group of Death was a nice accomplishment, as was beating the Czech Republic. But at some point in these marquee events, depth begins to take over.

Portugal doesn't have enough of it. Spain and France do.
