Sean Dyche has officially been at Everton for 14 days. He learnt his harshest lesson so far in just 13 cruel seconds at Anfield.
That was how long it took between the ball thudding off the Liverpool post and it being poked past a bewilderingly stranded Jordan Pickford by Mohamed Salah in front of the Kop. Everton, so close to taking the lead, were instead chasing a game they could ill-afford to leave themselves exposed in.
It would be easy to look at those 13 seconds and conclude they were the perfect example of the fine margins between success and failure in one of the world's most ruthless sporting competitions. To do so would be to overlook factors Dyche has no choice other than to acknowledge if he is to plot a path to survival for Everton, if he is to prove wrong the words sung with such glee from the home fans after Salah's opener - that this would be Everton's last top flight derby.
