Marta named in Brazil's squad for a sixth World Cup
Six-time FIFA World player of the year Marta will lead Brazil's quest for a first Women's World Cup title alongside other experienced players such as Debinha (31), Tamires (35) and Andressa Alves (30).
However, the former US and Sweden coach does not guarantee that the all-time Women's World Cup top scorer will feature in the starting lineup.
"Marta is the queen, she is an icon. Just being around her is contagious," said Sundhage on Tuesday.
"If she will be in the starting lineup I don't know, not yet. She will play the role I will give her and I am sure she will do well."
Brazil will start a training camp this week and face Chile in a farewell friendly on Sunday before travelling to Australia.
