To appreciate the magnitude of what Manolo Gabbiadini should have achieved – if football had not been so backward in its approach to video technology – you simply had to look at the rarefied list of hat-tricks in a major Wembley cup final. It has happened just once in the FA Cup – Stan Mortenson in 1953 – and never previously in the League Cup. The only other was Sir Geoff Hurst in the 1966 World Cup final.

Yet it was not Gabbiadini’s own personal frustration that fuelled Southampton’s burning sense of injustice; just the belief that a 41-year wait for silverware might well have ended had referee Andre Marriner – and his assistant Stuart Burt – not ruled out Gabbiadini’s clearly onside ‘goal’ in the 11th minute.

“At this level, that assistant has to get that right; he can’t even see Gabbiadini,” said Matthew Le Tissier, a pundit on Sky Sports. “The referee should go over and speak to him. That changes the complexion of the game. It is disgusting.”
