"They work hard, they fight hard and they have some good quality players who play in England and have good strengths. They have some quality in the counter attack and they complicated life for Mexico a lot."
The All Whites' display against Mexico made a lot of people at this tournament sit up and take notice - who is this team from the bottom of the world pushing the North American champions to the limit? - and Santos was keen to emphasise that point.
"We have to be on our toes because they are a team that can surprise," said Santos. "I hope we have no surprise."
Several Portuguese journalists kept referring to the expectation of a goleada (a big win) on Sunday, but Santos watered that down.
"We don't want to take things for granted," said Santos. "We always respect our opponents and we don't underestimate anyone."
Santos also refused to confirm if Ronaldo will take the field, though Portuguese media has indicated that he is likely to play.
"I don't know if I am going to play with Ronaldo or not," said Santos. "It's not I don't want to say, but I don't want the opponent to know that is why."
Santos also joked that he understood the Ronaldo mania around Russia, saying
"even I want to watch Cristiano Ronaldo."
