Richard Keys mistook Everton’s pre-match air raid siren for a fire alarm in the BeIN Sports studio for coverage of Sheffield Utd’s trip to Goodison Park.

The Merseysiders have been using the Second World War-vintage sound effect – also used by boxer and celebrity fan Tony Bellew – before kick-off since 2019.

Everton fans having a Twitter scrap with Richard Keys, who genuinely thought the siren on Z-cars was a fire alarm, will take some beating today. I mean, why bother?

Somehow this had eluded former Sky Sports anchor Keys, who was visibly alarmed as the noise blared out from the stadium appearing on the screen behind him.

His long-term onscreen partner and former Toffees player Andy Gray took great amusement in the confusion and can be heard laughing off camera.

In the match itself, Carlo Ancelotti’s men succumbed to yet another home defeat as the Premier League’s bottom-placed team ran out 0-1 winners.
