The football handbook isn't exactly clear on when a blip becomes a full-blown crisis. But Liverpool surely veered into that territory at some point during a wretched 90 minutes at Napoli.
Perhaps it was inside five minutes when, after striking the outside of the post just 42 seconds in through Victor Osimhen, Piotr Zielinski scored from the penalty spot following James Milner's handling?
Maybe it arrived when Andre-Frank Anguissa sauntered beyond three players with a basic give-and-go before sliding it past Alisson Becker with just half an hour played?
