It has been a large rebuild for Ange Postecoglou at Celtic following a disastrous marketing campaign final time period.
Nevertheless, with simply two switch home windows he has revamped the squad and brought them to the brink of the Scottish Premiership title.
With the Scottish Cup semi-final in opposition to Rangers across the nook and the Premier Sports activities Cup trophy already within the Parkhead cupboard, a shock Treble is an actual risk this season.
It would not really feel that way back that Rangers consigned Celtic to their first trophyless season in over a decade with a Scottish Cup fourth spherical win in April 2021.
However if you have a look at the crew from that day it virtually feels as whether it is from an alternate timeline.
Solely Callum McGregor began the 2-0 defeat at Ibrox on April 21, and the 2-1 victory for Celtic on Sunday.
Bain was given the nod forward of Vasilis Barkas and Conor Hazard as Neil Lennon looked for his primary goalkeeper halfway via the marketing campaign, however is now warming the bench rather than Joe Hart.
Loanee duo Diego Laxalt and Jonjoe Kenny took up the full-back positions, however Greg Taylor and Josip Juranovic have made the positions on the flanks their very own within the new system with Postecoglou's patented inverted full-backs.
Everton defender Kenny will not look again on the afternoon in Govan fondly having netted an personal purpose.
The partnership of Kris Ajer and Stephen Welsh has been changed by the resolute defensive duo to Cameron Carter-Vickers and Carl Starfelt to finish the backline.
Scott Brown anchored the midfield three, with Ryan Christie and present captain McGregor given the nod by Lennon.
Southampton loanee Moi Elyounoussi and David Turnbull have been positioned in attacking midfield roles, whereas Odsonne Edouard led the road.
Edouard would miss from the spot to cap off a lacklustre last season at Parkhead.
