The former Corinthians manager, who took control of the national team in 2016, has done enough to earn a new deal that should take him to Qatar 2022.
“I understand the CBF has given us the conditions to build an environment of union and extreme professionalism and we will continue,” he told the Brazilian Football Confederation’s (CBF) website.
