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.
City’s No.31 is hoping the team can emerge victorious this time around.
But, despite the pace and grace of the Samba Boys, Ederson insists the players need full focus.
He said: "We know how difficult it is, but we have a good team with total capacity of reaching the final and trying to win it.
"And we need to have this mentality, a victorious mentality.
"We need to think that we are going to be there, we will work to be there and that's what we'll do."
After a break now for club football, it’s full steam ahead for the 22nd edition of the global football competition.
Every player has hopes and dreams of lifting the famous trophy - and Ederson is certainly no different.
He added: "I haven't thought about it yet. But a World Cup is a World Cup.
"When you talk about the World Cup, what comes into the mind of any player that can play it, is the image of him lifting the trophy - and it's no different to me.
"When I think about the World Cup, I imagine Brazil lifting the trophy."
