It was a Cup night, so did you expect anything other than surprises? Nothing ever goes to plan at Anfield on occasions such as these and so it was true.
There was a surprise for Alexander Isak, who found himself being ordered to do more running at half-time when he thought the sanctuary of the changing room beckoned. There was a surprise for Will Still, who saw his Southampton team leave their patchy form well behind.
But the biggest shock was reserved for Arne Slot, who watched in disbelief as Hugo Etikite saved the day in moment then, in the next, presented his manager with a unnecessary headache from two actions that even his team-mates regarded as preposterous.
