Spain midfielder Andres Iniesta claims he knows how Portugal will play in their upcoming match.

The defending world and European Champions face their fellow Iberians on Wednesday, and Iniesta is adamant that the Portuguese will adopt a similar defensive style of play to the one they used in the last 16 of the 2010 World Cup, when the Spaniards were able to defeat them 1-0.

Speaking at a press conference, he said: "Portugal’s style or idea is more or less the same as it was in the World Cup. We will see how they set up but I think they will [sit back and] wait for us, they will try to close the space inside so that we have less fluidity to our play.”

"They have a very strong and hard-working central midfield – they have players who are at a very high level. If we don’t play well, Portugal will control the game and that is exactly what we don’t want."

The Seleccao did some beating as revenge though on a friendly match previously, where they massacred the La Roja 4-0.

Iniesta though is skeptical that that result will have any bearing on the coming encounter. He did warned that La Roja must learn from their mistakes that day.

He added: "Fortunately that was some time ago; it was a different game and it has nothing to do with the game we will play tomorrow. All of the things are important to analyse, though. We have been warned of what can happen if Spain play without intensity, without concentration.”

"They are one of the best teams, they have players who can decide games and it’s a very demanding fixture. We have to be fully focused for 90 minutes and concede virtually nothing if we want to win the game.”

On the other hand, Besiktas striker Hugo Almeida has confirmed that he will be starting for Portugal on Wednesday.

Seleccao coach Paulo Bento had been looking at his options after Helder Postiga sustained an injury against the Czechs, which will rule him out of the semi-finals.

Almeida is happy to have been given his chance against to fight against the champions and hopes to make the most of it.

"I am satisfied," he said at a press conference. "This is what I have been working for. I will show my worth on the field and will give my all.

"To win the match, we need to score goals. This is our first target. We know what Spain are worth, but we deserved to be here. We will do anything to win."

"I will do my best, and if I can score a goal, that is even better. With my head or my feet. What matters is to score."

Portugal's clash against Spain on Wednesday kicks off at 20:45CET.
