They’ll be remembered forever as Celtic’s Invincibles.
Over the last 129 years Celtic have been battling against the odds for trophies but only the class of 2017 has completed a domestic campaign unbeaten.
No side will ever compare with the Lisbon Lions but they did lose home and away to Dundee United as they claimed all five trophies in their never to be forgotten or emulated season of joy.
There has been a few moments of concern on the way to winning the title but an iron will and unbreakable desire to succeed have taken them to heights that no one other than Kolo Toure was predicting in pre-season.
Yesterday at Hampden they survived a few scares. Jonny Hayes put Aberdeen in front but Stuart Armstrong quickly equalised.
Bobby Madden was always going to be a problem to overcome, his comments about Leigh Griffiths on the eve of the match confirmed the arrogance of a man out to draw attention to himself.
His failure to spot Hayden Stockley’s attack on Kieran Tierney was entirely predictable but Celtic refused to buckle, they increased the pressure as the second half developed then with immaculate timing Tom Rogic created history and memories that will be celebrated for years to come.
