Spain go into tonight's game hoping to continue their winning form just 6 days from their first World Cup clash.
There aren't many tougher tests to begin with than the Netherlands, the side that finished runners up to La Roja last time out.
After a comprehensive 2-0 victory last time out against Bolivia, Spain come up against a side ranked 69th place in FIFA's World rankings, and have no trouble swiping aside La Selecta, particularly with the news that Diego Costa looks likely to be selected by coach Vicente Del Bosque.
Del Bosque is quoted as saying "We don't want them to risk injury but we want to see them in a game and I hope the outcome is good. If we can see them in the match against El Salvador, then even better."
And despite the obvious nerves approaching as the greatest show on Earth draws ever closer, Del Bosque is happy with his Spanish sides preparation "The first match against Holland is what worries me most," said the coach. "They're a team who are well-organised, well-run and will surely pose many difficulties. "However, you wouldn't think we were at the end of the season. The players are physically capable, training well and will arrive in Brazil in good condition. "The competition is tough but in terms of fitness levels, I don't think we have to worry. We know we will play in conditions with a lot of heat and humidity."
Midfielder Xavi is keen to have revenge on Brazil, after A Seleção beat them in the 2013 Confederations Cup "Anything could happen, but football always gives you the opportunity to get revenge," he said. "Hopefully it's at the World Cup and at as late of a stage as possible. It was a game in which everything went against us and they got all the breaks. "But the whole experience will stand us in good stead for the World Cup. We've had a good taste of the weather and we know what we'll be up against if we face Brazil."
Opponents El Salvador are unlikely to pose too much of a problem for the Spanish, with a world ranking of 69 and just one win in their last eight matches.
The Central American republic were beaten 2-1 by the Ivory Coast in midweek in what was their first game under new coach Albert Roca.
All in all it should be a routine victory for La Roja, with tougher tests surely to come in Brazil, where they are widely considered as favourites to retain their 2010 World Cup crown.
