The last time Arsenal faced Liverpool under the Friday-night lights, the year was 1989 and the old Division One title was on the line. It is a telling indication of quite how much has changed in the subsequent 28 years that a meeting between these two giants of English football has since been reduced to a mildly-important tie in the race for fourth place.

And yet even those great teams of old would have salivated at the prospect of fielding an attack as bone-chillingly terrifying as Jurgen Klopp’s ‘Fab Four’, a quartet that could boast the same imagination and speed with which Philippe Coutinho, Roberto Firmino, Mohamed Salah and Sadio Mane rip into Premier League defences.

How they would have utilised such strike power, such swagger. And how they would have winced at the abominable defending behind them. They say football matches can be a game of two halves, but Liverpool are making a fine attempt at becoming the Premier League’s team of two halves.

This rip-roaring encounter was the sort of unpredictable meeting we have come to expect from a match between north London and Merseyside’s most successful sides, which is fast becoming the Premier League’s most consistently-entertaining fixture.
