It will be a brilliant pub quiz question in years to come: who is the only footballer to finish Invincible at two different clubs?
And the answer is the Ivory Coast defender Kolo Toure, who managed the astonishing feat with Arsenal in 2003/04 and Celtic in 2016/17.
Toure played the closing minutes of the record-clinching 2-0 win over Hearts before showing off his dance moves in the changing room to the tune of 1990s hit No Limit.
Celtic have become the first side since Rangers in 1899 to negotiate a Scottish Premiership league campaign undefeated. They are also the first side to manage it over a 38-league campaign.
Celtic manager Brendan Rodgers will become only the third coach in the club’s history after Jock Stein and Martin O’Neill to win the domestic treble if they see off Aberdeen in the Scottish Cup final at Hampden Park on Saturday.
