Dunga says he would prefer Neymar to report for international duty without the off-field issues that have affected him in recent months.
Brazil coach Dunga has suggested he is frustrated with the off-field problems regarding Neymar, but is confident his captain can cope with them and flourish for his country.
The Barcelona star was named in Brazil's squad for this month's World Cup qualifiers with Uruguay and Paraguay, as Dunga's men continue to build up to the Copa America Centenario in June.
Neymar will likely lead Brazil at the Copa and the Olympics in Rio, but has been involved in investigations relating to tax evasion charges and alleged financial mismanagement of his transfer from Santos to Barcelona.
