Willian has spoken highly of Brazil national team manager Dunga.
Ahead of Copa America 2016, which starts this weekend, the Chelsea star admits he is delighted to play under Dunga who has an esteemed career having won the 1994 World Cup and two Copa Americas (1989, 1997).
"I'm very happy because since Dunga took charge I've started every game so it's very good for me," said Willian.
"With every match I gain more confidence and now, when I'm with the national team, I am able to play with more freedom.
"Dunga is a very good manager and a good person. He has a big heart, he's a Brazilian legend so I enjoy it a lot playing under him."
Brazil have been drawn in Group B for CONMEBOL's 100-year anniversary of the tournament, which this year takes place in the USA.
They come up against Ecuador in Pasadena on Sunday before taking on Haiti and Peru in their other group stage games.
