i don't think any keeper would save that more than 2 times out of ten nevermind Krul saving it 10 times out of 10, it was a glancing downward header from about 5 yards. it was virtually in the back of the net before the keeper knew anything about it!
Krul gets to that with his better reactions, agility and wingspan. No doubt about it. Harper almost got to it, and those are his weak points.
