If you think Ings poses no more injury risk than any other player (and I thought he'd just been unlucky till I saw the injuries he picked prior to joining Liverpool), then you're clearly on the wind-up.
Again, to repeat, its perfectly consistent to rate the player but have concerns about the structure of deal if, as reports suggest, the club has little protection in the event of an injury. Not a particularly difficult position to understand unless you're being obtuse.
