Redmond impressed hugely during the recent European Under-21 Championship and was arguably England's best player.
Hughton and Redmond were together at Birmingham, and now a deal is understood to be close to completion.
"I worked with him at Birmingham. He has done very well and he is a very exciting young player," Hughton told Sky Sports News.
"But any progress that we make on any player, we will only notify you when any business has been done."
