Bauza was named on Monday to replace Gerardo Martino, who resigned a month ago after steering Messi’s side to two successive Copa America finals which ended in penalty shootout defeats to Chile.
The more recent of those results in the Copa America Centenario in the United States in June led to Messi deciding to quit the team. It was his fourth defeat in a major final with Argentina.
“I’m optimistic about Messi,” Bauza said. “I hope the chat with him will help for him to carry on in the national team.
“I want to explain to Messi what my (tactical) idea is. The least of my worries is his position on the pitch,” Bauza was quoted as saying in the Argentine daily La Nacion on Tuesday.
“There’s no need to convince Messi of anything, the plan is to talk about football,” said Bauza, speaking in Brazil where he has coached Sao Paulo for eight months.
Bauza, who quit his job with Sao Paulo to accept the Argentina vacancy and will sign his contract in Buenos Aires on Friday, has only a couple of weeks to decide on his squad for qualifiers at home to Uruguay and away to Venezuela in the first week of September.
“There isn’t much time. My first squad won’t have many changes but I want to talk with five or six of the leading players,” Bauza said, no doubt referring to the likes of Javier Mascherano, Angel Di Maria and Gonzalo Higuain.
He also opened the door for Carlos Tevez, overlooked by Martino since a World Cup qualifier against Paraguay in Asuncion last October where he won his 76th cap.
“I’m thinking of Tevez as I am about other players … Tevez is a player good enough for the national team,” Bauza said.
Bauza, a former central defender, rejected a tag as a defensive coach, saying: “I’m one of those who think that all (the team) have to defend. Football today is like that.
“You can defend in your opponents’ half if the pressure is high (up the field) but it’s easier when you have players of the quality of the Argentina team. The options they offer you are many.”
Argentina are third in the 10-nation South American World Cup qualifying group with 11 points from six matches, two points behind leading pair Uruguay and Ecuador.
The top four teams after 18 matches go through to the Russia finals while the fifth-placed team goes into an intercontinental playoff for one more berth.
