Brazil are in Group G alongside Serbia, Switzerland and Cameroon for the tournament, which runs through November and December during a Premier League mid-season winter break.
They face Serbia in their opening game on Thursday with a 19.00 (UK time) kick-off at Lusail Stadium.
Brazil are five-time winners but have not seen success since 2002 when they defeated Germany 2-0 at International Stadium, Yokohama courtesy of a Ronaldo double.
