Hull boss Nick Barmby is trying to land King after he returned from his stint at Borussia Monchengladbach.
"We have got a chance and if we can do it, then great," Barmby told the Hull Daily Mail. "We've got a chance for other players as well so have cover, but I've seen Josh King play quite a few times. I really like him. He's a very good player who's quick, got a good stature and can play in a number of positions. <> "He's an exciting player but we'll have to wait and see if we can get something done."
