The two sides - described as "giant powers of European football" by La Roja's boss - go head to head in an eagerly anticipated encounter at Stuttgart Arena on Saturday.

Spain, which topped Group B with maximum points, is the only nation at the tournament to have won all four matches thus far, while Germany collected seven points in Group A before overcoming Denmark 2-0 in the last 16.

Both teams are seeking a record-breaking fourth European Championship triumph, and whoever prevails here will be widely expected to go on and lift the Henri Delaunay cup on 14 July.

De la Fuente is relishing what will be a repeat of the 2008 final, which La Roja won 1-0 thanks to Fernando Torres's sole strike.

"It could have been the final of the European Championship, and it'll be an even game on a footballing level," De la Fuente said.

"Germany always start games in a really powerful way, so obviously we'll try to counteract that. We'll try to take the initiative and go all-out from the first minute.

"These are two giant powers of European football and the first thing I'd say about my team is that one of our great strengths is that we always perform as one unified block. In that respect, us and Germany are in fact quite similar.

"I wouldn't change my players for anyone in the world. For me, my players are the best in the world. We're fully prepared to go out there and try to win. We feel lots of responsibility, and we're extremely focused."

Asked if he thought the winners of this game will go on to lift the trophy, the coach added: "There are other powerful teams in other ties. The closer you get to the final, only the best remain.

"Nothing is free here. Whoever goes through will go through because they're a great team. In football, the best team doesn't always go through.

"I don’t know if [the winners] will be one of the favourites to win the title, but we see ourselves as a very strong team with the potential to fight for it."

Dani Carvajal concurred with De la Fuente, and the Real Madrid defender believes the contest will be determined by the finest of margins.

"I have a great feeling [about the game]," he said. "I can see from my team-mates that everyone is relaxed.

"We know we have to play a great game to beat them, but I can see a confident and energetic team. It's a 50-50 game in which details will make all the difference.

"Man for man, they have world-class players. They have fast wingers, tough centre-backs and people who like to have the ball at their feet. We have similar qualities to them.

"It depends on if they will sit back or press high. That's going to define how close we get to their goal, and maybe the pace of the game."
