Redknapp has confirmed he plans to stay in charge for their Championship campaign.
"My target is to get promotion next year. That's the aim. I don't intend to stick around for four years in the Championship.
"I want to build a team to try to get up. It will be hard, I'm not silly enough to think it will be easy.
"It's a tough league. With a bit of luck, if I can get some players in, change things around then we'll give it a good go. But it won't be easy."
