Krul has always looked shaky, long before he joined us and since he's been here.
Its easy to point out the good saves he makes but his overall game is incredibly inconsistent and we should've been looking for an upgrade on him the previous time we were promoted.
Settling for him as our number 1 because he makes a few good saves now and again is negligent. His mistakes aren't noticed too much in the championship simply because he faces less action.
In the Premier league his frailties are all too often exposed.
