The contract renewal will put the 66-year-old Italian at the helm of the team “until the 2030 World Cup,” the CBF said in a statement.
Ancelotti took over as Brazil coach last year and oversaw the five-time world champions’ successful qualification for next month’s World Cup in the United States, Canada and Mexico.
“From the very first minute, I understood what football means to this country. For the past year, we have been working to lead the Brazilian National Team back to the very top of the world stage,” Ancelotti said in the statement.
The former Real Madrid, AC Milan and Chelsea coach said he wanted “more victories, more time, more work.”
CBF president Samir Xaud said the renewal was part of efforts to “keep Brazil at the highest level of world football.”
Ancelotti is due to announce his final squad for the tournament on May 18, before Brazil play a warm-up match against Panama at the Maracana Stadium on May 31.
The Brazilians will be based in New Jersey during the World Cup, and face Morocco, Scotland and Haiti in Group C. (AFP)
