Redknapp claims Norwich City are one of the sides interested in acquiring his services.
“We think Caulker’s got a great future, but I would be happy to loan him out,” said Redknapp. “He played at Bristol City last year on loan, did really well and had a great season for them.
Redknapp made it clear that a loan move to Swansea would be acceptable.
“I’d let him go to Swansea – no problem,” he said.
