Cesar returned to the side in place of Robert Green at West Ham and justified his inclusion with a number of fine saves as the visitors claimed a 1-1 draw.
Redknapp told the club's official website, www.qpr.co.uk: "You look at his CV and it's absolutely remarkable.
"He's won absolutely everything there is to win in the game and he's still relatively young for a keeper.
"He's world class - a top, top goalkeeper.
"I'm lucky here, because I've got two top class keepers.
"Rob (Green) was fantastic for us at West Brom in the Cup and Cesar, again, on Saturday was brilliant."
