If he does, it'll either be a disaster or a prolonged irrelevance. Benitez is an erratic, high-spending manager whose gifts aren't enough to elevate the existing squad to major trophies. That plus the weight of expectation would see him fail.
Honestly think Carroll starts to dive, realises Krul has missed him and the ball is still at his feet, takes another touch (that last half-tap) while falling, perhaps imagining he can still right himself, then realises he can't and goes through with the dive. Bad play or bad simulation, either way it's no good 😃
