Cast your mind back to Christmas. The world had never heard of a coronavirus and the Scottish Premiership was living up to its billing of having its tightest title race in quite some time.
Rangers had just beaten Celtic to move to within two points of the relentless champions, with a game in hand, as the two sides set about embarking on their winter break.
It was all set up for a truly fascinating conclusion to a Scottish Premiership campaign, where the status quo could be challenged, however Bhoys boss Neil Lennon had other ideas.
Think back to when COVID-19 closed football down and Celtic have all but sewn up the title, holding a 13 point lead on their Glasgow rivals, who will still be 10 adrift even if they win their game in hand.
The additions of Patryk Klimala and Ismaila Soro could be considered as influential in the reason for the Bhoys recent dominance, but they have played 15 minutes of league football between them.
The key difference was the inspired move by Lennon to switch formation, recognising the need to change if Celtic were to continue their dominance of Scottish football.
He made the move to go with three at the back during the winter break, and although an exit from the Europa League was a blow, they have not looked back in the league since then.
There is uncertainty surrounding the future of football at present, but one thing which is no longer in doubt is when the game returns in Scotland, the Bhoys will once again be crowned champions.
