Since before the first whistle at Hampden on Saturday Celtic fans have been celebrating with social media swamped by clips of hoops supporters enjoying the latest success.
Never before has the treble been successfully defended but that’s exactly what Brendan Rodgers’ side achieved on Saturday with a 2-0 win over Motherwell.
Across the west of Scotland there were scenes of great joy with a particular concentration in the triangle between Celtic Park, Hampden and Glasgow city centre.
With the mercury going close to 20 degrees there was no reason not to party as first half goals from Callum McGregor and Olivier Ntcham put the outcome of the match beyond doubt.
Celtic fans occupied more than three sides of Hampden, giving their team incredible backing throughout at a stadium which was considered a bogey ground just two years earlier.
Once the final whistle blew the celebrations really kicked off with the added bonus of an open top bus to parade the players back to Celtic Park.
It was an unforgettable day in many ways, thanks to video and social media no one will be forgetting about it any time soon.
