De Bruyne was in scintillating form against Arsenal on Sunday, scoring twice and providing one assist.
Former England international Redknapp wrote in the Daily Mail: "There are two midfielders who stand out to me in world football right now and they are Manchester City's Kevin De Bruyne and Frenkie de Jong of Barcelona.
"These two are different class. Their brains are so in tune with modern football.
"The intelligence of their runs, the timing of their tackles, the way they read the game and know what is about to happen as if they have a crystal ball tucked in their socks.
"They are smoothness personified. They love to have the ball and never give it away. Now imagine them together. Wow. That balance would be a dream for any manager.
"De Bruyne is the better goalscorer of the two and he has to be seen as the ultimate midfielder, the best in the Premier League. Manchester City boss Pep Guardiola is blessed to have him and he knows it, too."
