Edgardo Bauza has total faith Argentina will reach the 2018 World Cup, despite his side's poor qualifying campaign so far.
A humbling 3-0 defeat to Brazil in Belo Horizonte on Thursday left Argentina in fifth place in the South American table, with just four wins to their name from 11 matches.
"I never put qualifying for Russia 2018 in doubt," he told a news conference.
"The points we've lost hurt, but we still depend on ourselves. The group is strong and that gives us confidence.
"We've lost points that we didn't think we would and it's normal that criticism has come out. Hopefully in San Juan the people can spread the importance that this shirt has. We need that support.
"We haven't had a regularity in our play. The players have to impose the ability they have. The players know their condition and they know what they can do. I trust that.
"I work thinking about going to win the next game, as always. We're really looking forward to it. We're thinking about playing a good game and winning."
Jose Pekerman's side drew 0-0 with Chile in Barranquilla in their last outing.
