Russia bounced back from that setback to reach the quarter-finals, where they beat Holland 3-1 in extra time, and now face Spain in tomorrow's encounter at the Ernst Happel Stadium in Vienna with a place in the final up for grabs.

Villa, the top scorer in the tournament with four goals, feels Spain's pool win over Russia was not as easy as the scoreline suggests.

"This is a different game altogether," said Villa, who scored a hat-trick against the Russians.

"This is a semi-final and we cannot be over-confident.

"Our opening game wasn't that easy despite our 4-1 triumph.

"We have seen that Russia have grown game by game so we expect a very complicated encounter."

Knocking out world champions Italy on penalties to progress to the last four allowed Spain, who have underachieved in the big tournaments over the years, to break a psychological barrier.

With the nation having waited 24 years to see Spain return to a European semi-final, Luis Aragones' men appear ready to deliver.

"Russia is a team that has proved to be in top form," said Liverpool striker Fernando Torres, who will partner Villa up front.

"But if we beat them once, I am certain we can beat them again."

Aragones is set to play with his strongest line-up in the hope 'La Seleccion' reach their third European final.

Spain, though, will have to keep a close eye on Russia playmaker Andrei Arshavin.

The 27-year-old, who missed the first two games through suspension, terrorised the Dutch defence - setting up the second goal for substitute Dmitri Torbinski before netting the clinching third himself.

"There is little we can say about him," said Spain captain Iker Casillas. "We have all seen what he did against Holland.

"The most important thing is that we do things well, that we focus on our game and not on our opponents."

Casillas, the star of Spain's quarter-final win over Italy after saving penalties from Daniele De Rossi and Antonio Di Natale in the shootout, is convinced Spain can go all the way.

"We are very proud of what we have achieved so far," said the Real Madrid stopper.

"We hope that we will have luck in the key moments because you need some fortune to get to a final.

"Now we have a big task ahead of us, but we have the whole nation behind us and we feel their support."
