Holtby is shit.
It's been 4 years since I first started watching him play, not one incident springs to my mind of anything productive he has ever done.
Agreed, he seems to be one of these players you get occasionally whose reputation inflates in directly inverse proportion to the actual achievements he manages.
I have to admit I don't know enough about him to make a judgement, so if he's terrible and a player who will be permanently consigned to the bench then it's a waste of money. Would he be worse than our current midfield, without Delph though?
