Normally a season-long loan is just that, it's part of his development. He should be well-tuned up for us in the Championship next season...
Who brought him in? Probably not Redknapp as he wasn't interested in kids or the future, certainly not Ramsay or Ferdinasnd, they weren't here.
He was one of our earliest summer signings so you have to assume Harry was involved, his loan to Huddersfield was fixed up before the start of the season...
