If Liverpool win the Quadruple this season, or if they or Manchester City win it anytime soon, it will obviously be a fantastic achievement.
But it won’t be any greater than Tottenham’s Double win of 1960-61, Arsenal’s in 1970-71, or Liverpool’s in 1985-86. Nor will it be any greater than Manchester United’s Treble triumph in 1998-99 which, pound for pound, would still be the greatest achievement of them all.
I’m not even sure it would be the greatest Quadruple ever, either, because that accolade surely has to belong to the Celtic team of 1966-67. The Lisbon Lions won the Scottish top flight at a time when it was the equal of the English First Division, two domestic cups and the European Cup … with just 14 players.
