Redknapp says he has no regrets passing on the Frenchman.
"The boy at Newcastle's a good player as well, he's a talent, Ben Arfa. He's similar, another good little dribbler," he told London24.
"We probably could have had him as well, but you can't take everyone can you? You end up with dozens of players hanging around, and we've got good players here anyway so he might not have got in our team."
