Nope, not joking at all. In fact, let's break'm down.
Jens Lehman, arguably top 4 goalie in the tourny, or even the world. Dudes solid and has always shown it. Plus, head to head against Casillas, I think/know Jens is better.
Germany's defense follows the traditional, uniform German wall. They have a very fast and solid dude in Lahm, who creates a lot more possibilities than Ramos, they don't have the greatest center back as Spain does in Puyol, but that's wht makes it better. Spain has to rely on just one guy when Germany uses all 4 guys.
Frings, Ballack, and Schwienstieger are all better than Fabregas, Iniesta and Garcia, IMO. Germany works much better as a team and it is evident in their midfield, while Spain is more free and sporadic.
While Torres and Villa seem like an unstoppable force, Podolski and Klose are still much better strikers. They use the entirity of the pitch more and come back to help alot. Plus, Klose, aside from being an animal, is also a great passer, so he's always got his eye on the open Podolski.
You can say Casillas is indeed the better goalie compared to Coupet.
I don't think there's a defense out there better than France's. Thuram, Sagnol, Gallas, Abidal, and Evra are world class players, whos defensive talents are only rivaled by the Italians or the Germans.
Ribery > Fabregas, anyday of the week. The dude is a genius and is being hailed as the next Zizou. They also have worlds of experience in their midfield. Viera, and Makelele are multiple world champions, no one holds down the middle better than those two.
France has Thierry freakin Henry, better than Villa and Torres combined. Now aside from that, they have Anelka, Benzema and Gouvou, all world class strikers.
Gigi Buffon, one of the best goal keepers ever. Dude makes Casillas look like a child. Reyes as well.
Italy is notorious for their defense. Caniving and calculating, when theyre on, theyre on. They work like a special ops team, technically dissassembling the attack and creating their own. Theres absolutely no question here, who is the better defense.
Italy's midfield works a bit like their defense, but they have two aspects, they have the engine, which is Gattuso, and the maestro, which is Pirlo. Fabregas has literally nothing on Pirlo. Iniesta, who I believe is better than Cesc, still isn't AS seasoned as someone like Cameronnesi.
You can possibly make a claim that Villa and Torres are better than Toni and Del Pierro, and I might agree with you, but with the rest of the team behind them, it's really hard to be 100% sure.
Goal Keeping: Edwin van der Saar. Arguably the best goal keeper in the world right now. Reyes and Iker don't even come close.
The Dutch defense was a bit questionable, but after yesterday's game, it is clear that Oijer, Van Bronkhorst and Boulahrouz are more than capable. Oijer showed that you can leave him alone against 3 guys and he's perfectly fine. And Giovani showed he can be right up there, helping with attack.
Sneijder, Van Der Vaart, Kuyt, Englaar, come on. Sneijder and Van der Vaart have been known to run teams all by themnselves (IE. Hamburg and Ajax). Kuyt is the dynamic midfielder/striker that can play almost anywhere on the pitch.
Ruud Van Nistelrooy, one of the greatest strikers EVER to play the game, dude can smell a goal from a mile away, leaps and bounds better than Torres and Villa. But now you got Babel, Van Persie and Jan Venegoor. That's one of the most deadliest attacks in all of Europe.
You can also make a claim that Portugal's midfield is worlds better than Spain's, as well as their defense, but since they have literally ZERO strikers, I'll leave them out.
Spain are perrenial losers, they always have an amazing team, but they just can never pull it together, never. They don't quite have the chemistry and quite frankly they almost always switch up their roster, so you hardly ever get a formula going.
Hope that helped
