Spain coach Vicente del Bosque has distanced himself and his players from political concerns about their friendly match in Equatorial Guinea.
The world and European champions' trip to Malabo has been met with condemnation from the international press and human rights groups because the country's unelected president, Teodoro Obiang, has been accused of human rights abuses, including kidnapping and torture.
``We are just sportsmen and we haven't come here to give prestige or strengthen the position of anyone, nor to overthrow anyone, we have come here to play football with total freedom,'' said Del Bosque in a press conference.
Questions have also been raised about how useful a game against a side ranked 199th in the world is for Del Bosque's team, who in seven months time will be fighting to retain the World Cup in Brazil.
But Del Bosque, who also announced that he had agreed to extend his contract as national team coach until after Euro 2016, defended the trip.
``Being able to be together as a team serves us well so that we can re-establish relationships and get comfortable being together,'' he said.
He revealed he had watched two of Equatorial Guinea's World Cup qualifying matches.
``They have their limitations but they are strong in certain aspects and they could make things complicated for us,'' the Spain coach said.
``They are well organised and focus heavily on wing play, they press well, play on the counterattack but don't have any fear.''
After Saturday's match Spain travel to Johannesburg, the scene of their World Cup triumph over Holland in 2010, to play South Africa.
Del Bosque has taken a 23-man squad to Africa for both matches and said he intends on using every player, including Bayern Munich midfielder Javi Martinez, who was forced to end Thursday's training session prematurely owing to discomfort in his left knee.
He added: ``We've got 23 players out here, any of them could play, we don't have first choice or second choice players. Both of these games are equally important to us, we have the added responsibility that comes with our recent success.''
Atletico Madrid striker Diego Costa was chosen in the initial squad and was set to make his Spain debut on Saturday after officially declaring his intentions to play for Del Bosque's side over his native Brazil, but had to pull out of the squad at the start of the week with a thigh injury.
Del Bosque admitted the injury to the 25-year-old was a blow to Spain, who had to engage in a tug of war with Brazil for the player, but tried to be positive.
He said: ``Whenever you lose a player to injury it's a setback. We were confident that Diego would be here with us. But it's (Costa playing for Spain) a long term decision, not just for November, and we hope we'll be able to make it a reality.''
