While Ederson is the undisputed first choice at the club, Bravo gets his chance in less important games.
He shone for City as they won on penalties against Liverpool in the Community Shield.
De Bruyne believes that Bravo is good enough to keep Ederson concerned for his place in the team.
"It's incredible to have a goalkeeper there with so much experience," De Bruyne said to reporters.
"He's been unbelievable in preseason and he will keep Ederson on his toes."
