Spain coach Vicente Del Bosque was keen to stress the threat Chile pose to his side`s hopes of reaching the last 16 of the World Cup, claiming Marcelo Bielsa`s in-form outfit can cause problems for any team.
Del Bosque also warned against reading too much into the result of their last meeting with Chile, when the European champions recorded a 3-0 friendly victory in Villarreal 18 months ago.
"That result does not reflect what happened in the game, because the Chilean side are very good, as they have shown in the first phase here," said Del Bosque, ahead of what could be a decisive encounter on Friday.
Chile currently lead Group H with a maximum six points from their two games, with Spain and Switzerland locked on three points and Honduras still looking for their first points but not yet out of contention either.
"It`s going to be an even game, very open and difficult for both teams. They are two different styles of play, but both good," added the Spain boss.
"They are a difficult team for anyone to face because they have two weapons which are putting pressure on you and hitting you on the counter-attack.
"They try to overcome their opponents by stealing possession and hitting them quickly on the break."
Del Bosque also thinks the South Americans have enough strength in depth to be able to cope with the loss of key duo Carlos Carmona and Mati Fernandez, who are both suspended.
"They are two excellent players that they are missing. Carmona has done a great job, and Matias as well. But having said that, they have other players who can fit in just as well. They will not notice the absentees," the former Real Madrid coach said.
