The 58-year-old tactician has been criticised for ignoring the San Siro hitman when the South Americans could only manage a draw with Peru while they also lost to Paraguay in a recent World Cup qualifier.
Despite his prowess in front of goal, Icardi has only earned one Argentina cap to date - coming on as an 82nd-minute substitute in a 3-2 World Cup qualifier defeat away to Uruguay in October 2013.
The 23-year-old's attitude has sometimes been called into question and Bauza made it clear that he makes the decisions, and Icardi will only be called up when he feels it is right.
"If I want to call Icardi, then I will," he told ItaSportPress. "At this moment I prefer Gonzalo Higuain and Lucas Pratto.
"Carlos Tevez remains a very useful player and we all want to get this idea of retirement out of his head. I remain confident in my dream, as I am convinced we’ll be world champions."
