Spain speculation has 'surprised' Belgium manager Roberto Martinez

Belgium boss Roberto Martinez says he would be "very surprised" to be offered the Spain job amid reports he is the federation's preferred candidate to become manager of the national team.

Spain are looking for a new coach following their round-of-16 elimination from the World Cup at the hands of hosts Russia on Sunday. Luis Enrique, Quique Sanchez Flores and Michel are also contenders for the position, but according to Cadena Ser radio, Martinez is the Spanish Football Federation's (RFEF) No. 1 choice to replace caretaker manager Fernando Hierro.

When questioned about those reports, Martinez told Cadena Ser that he is not expecting an approach.

"I would be very surprised. I'm not that well known in Spain," he said. "When it came to football, I never considered what I could do tomorrow.

"I've gone from project to project, living the day-to-day with a lot of intensity. What I've learned is that in football you can only focus on today and what comes next depends on whether a given club or a national team that is interested in me puts forward a project that allows me to work in calmness and that there is a vision beyond losing three games. That is the way I've approached work."

La Roja sacked Julen Lopetegui three days before the start of the World Cup after the coach failed to tell the federation about his move to Real Madrid and appointed Hierro to guide the team in Russia.

Luis Enrique, Sanchez Flores and Michel are all free agents and, unlike Martinez, they do have experience coaching in Spain.

However, Martinez's tactics, that are based on dominating possession, would fit Spain's style.

"What is important in football is that you have a style where players can take it to the elite level," he said.

The 44-year-old recently signed a contract extension with Belgium to remain in charge until Euro 2020 and he said there is no buyout clause included in his contract.

"This question [about the Spain job] comes at the wrong time," he told Cadena Cope radio. "All that interests me now is to help the group, we are in the quarterfinal of a World Cup.

"In football, all that matters is the day-to-day intensity and then, when it comes to the future, you never know. What interests us is to beat Brazil."

Meanwhile, Vincent Kompany has urged Belgium to be on the front foot against Brazil in Kazan as they seek to reach the World Cup semifinals.

After averaging three goals a game in their four matches in Russia en route to the last eight, Kompany told L'Equipe they must not alter their attack-minded strategy against the five-time champions.

"I try to make people understand that nothing will change in our preparation. There was a lot of talk about finishing first or second in the group. I would have preferred to play Brazil in the final. We knew that by finishing first in the group our path would be tougher. It's our final. We scored a lot in the group stage and against Japan. Our biggest regret would be to play an insipid match and lose 1-0 like against Argentina in 2014. We would have the impression of having missed out on an opportunity," the Manchester City defender said.

"There's no shame in not beating very good teams. But we would like to play in our way, which has been our strength for a long time. If we talk about their individual qualities and the fact they are well organised, there's no point in comparing ourselves one on one. In that case, Brazil are going to win, we have no chance. But I can tell you that we're going to look them in the eyes. I am emphasising the collective spirit as I know how much of a deciding factor that will be on the match. They will have chances. I just want us to have as many and we'll see who wins."

He added: "From what I have seen, Brazil are compact everywhere. If we want to attack, we'll have to seize the moment and be clinical. We have never been kamikaze. There's no reason to be so against Brazil. Not one of us talks about tracking back or getting behind the ball. We want to score and win. There is also a lot of pressure on us. For the whole world, it's more on Brazil. But we want to win, and that ambition gives us some too."

Belgium produced one of the greatest World Cup comebacks ever in overturning a 2-0 deficit in the last 21 minutes of their round-of-16 tie with Japan. There is likely to be yet more drama in their quarterfinal encounter, a game in which Kompany said his country start as underdogs.

"In the ideal scenario, we get a very good result and we are able to play our brand of football. We have improved constantly since the start of the competition. I think we're able to take the next step," he said. "We're not afraid. We're want to come up against the best. We play for very big clubs. It'll be a very special day for us, but I believe in our chances. In Belgium, we usually think about defeat before playing. I believe 100 percent we can beat them."
