When asked about who might light up the World Cup, Carlos wrote in his column for the Sunday Mirror: "People talk about Messi, Ronaldo, Robert Lewandowski and Neymar, but for me, Willian is right up there".
But Tite sounded a note of caution as he looked ahead to Switzerland before games against Costa Rica in St-Petersburg and Serbia in Moscow.
Switzerland heads into the match with a lofty Federation Internationale de Football Association ranking of sixth in the world - a standing bolstered by some judicious selection of friendly opponents.
Neymar is the focal point of one of the most menacing attacks in the tournament, and lines up in a front four that includes Gabriel Jesus, Philippe Coutinho and Willian.
This year's Ticos won't sneak up on anybody.
The three German midfielders, Mesut Ozil, Toni Kroos and Sami Khedira between them didn't make a single tackle during the match against Mexico. "And then the opposition grew stronger and we were not advancing enough". Because the Ticos didn't lose in Brazil, they can tie the CONCACAF record for a World Cup unbeaten streak with a win or draw against Serbia. The 31-year-old started in goal for the team's 3-1 victory over Liverpool in this year's Champions League final.
Coach Joachim Loew has, like the Brazilians, transformed the team from 2014 to the extent that the man who scored the World Cup winning goal in Rio, Mario Goetze, is not in the squad. "We got a draw but this is only the beginning for us".
"But that is the moment, you end up taking decisions, sometimes, that are not the best ones, but only those who are there get to know how hard it is to play at these moments".
"We're not as good as we're made out to be, or as some think we are, " midfielder Toni Kroos said.
"I can't coach a team who complains".
The Central Americans topped a group including Uruguay, Italy and England last time to reach the quarter-finals, and this time are in Brazil's group.
Mexico though only lost one game in qualifying and have always qualified for at least the second round of every World Cup they have played. For the first time, he'll be joined by his younger brother and LA Galaxy teammate, Jonathan dos Santos.
