ROSTOV, Russia -- Mexico coach Juan Carlos Osorio has urged his players not to fall into a "comfort zone" after the highs of opening the World Cup with a 1-0 victory against Germany on Sunday in Group F.
El Tri shocked the reigning world champions in a deserved win and go into Saturday's second group game as the heavy favorite to overcome a South Korea side that struggled in a 1-0 loss to Sweden on Monday.
"We talked about how to not fall into the comfort zone and rest on our laurels," said Osorio in the prematch news conference. "This week we've talked about the topic, we've looked at two or three situations and emphasized what we did right against Germany.
"The boys responded well and we'll be fine tomorrow."
Osorio also said that the idea was to play "aggressive and attractive" football to represent Mexican and Latin American football in style and to win over new fans.
"I think the most important thing for this group of players is to be confident, credible and to [have] respect," said Osorio. "If we have those three factors I believe that there is a good chance of achieving the objectives. We have a good group of players and human beings."
Mexico captain Andres Guardado stressed that Mexico's players are focused and that the ambition of the squad in Russia goes beyond a victory against Germany.
"In the end we haven't achieved anything," said the 31-year-old. "We're not qualified, they don't give you more points for beating Germany and our worst enemy could be ourselves if we think the win has any extra value."
Osorio admitted he didn't know exactly how South Korea would be lining up tactically in Rostov, but said he had a plan A and plan B depending on how the Asian side approach the game.
"We're going to be playing a very robust opponent, even if we have all the chances to win," he said.
"They have a lot of strength, they are versatile, most of their players can play in different positions and in different systems. They have three possible formations."
The temperature is expected to be around 31 C (88 F) at kickoff on Saturday and South Korea coach Shin Tae-yong thinks the high temperatures will be a factor against his side.
"The deciding factor for tomorrow's match will be the weather," said Shin on Friday. "It will have an influence and the weather will work in favor of the Mexican team. There are used to the hot weather ... the weather will probably affect us negatively."
South Korea legend Park Ji-Sung also spoke to reporters in the media center in Rostov on Friday and stated that his team has to move on from that loss against Sweden.
"Yes, it will be a difficult game because we had a bad performance and a bad result in the first match and it'll be difficult to turn around the atmosphere," he said. "Also, Mexico won their first game against Germany, which is one of the best teams in this competition, so their atmosphere must be brilliant.
"But we have to prepare well and show our quality because I believe that our players didn't show their quality on the pitch in the first match.
"First we need to show our performance on the pitch and then need to wait because actually Mexico is a better team than us, but in football you don't know."
Germany faces Sweden later Saturday in the other Group F game in Sochi, with the reigning champions out of the tournament with a defeat.
