The Hoops boss says the goalkeeper will definitely move on this summer, with the Gunners and Roma heavily linked with a move for the Brazil international
Goal understands Arsenal have opened formal talks with the goalkeeper and are willing to pay £1 million for the Brazilian who they have identified as their No.1 shot-stopper target.
However, the Gunners will face competition for his signature from Roma after the Giallorossi's loan swoop for Chelsea newcomer Wallace stalled.
Meanwhile, Redknapp has confirmed he is fully expecting the 33-year-old to leave Loftus Road, and anticipates him moving to a top club.
"Julio Cesar will move on," Redknapp told talkSPORT.
“He’s a top class goalkeeper, Brazil’s No.1. He’s been in great for Brazil and I presume there’s a big club out there for him.
"He won’t want to play in the Championship, he’s a goalkeeper for a big club.”
