The Hoops are under new management this season after Brendan Rodgers replaced Ronny Deila at the helm.
After a shaky start that saw them lose to minnows Lincoln Red Imps, they have quickly flourished under the Northern Irishman with a series of impressive displays.

That continued on Saturday as they secured a 4-2 win over St Johnstone to make it two wins out of two in the Scottish Premiership.
And Forrest has hailed their pre-season schedule as the catalyst for their strong start to the campaign.
“Confidence is going through the full team just now since the start of pre-season,” he told the club’s official website.
“I just think since day one of pre-season it has been hard training and everybody has been benefiting from it – fitness and football wise as well. The more games we play we can kick-on from there and I think we did that today.”

It now remains to be seen what kind of season that Celtic can enjoy under Brendan Rodgers this season.
This season is looking likely to be one of the most exciting in a number of years, with Rangers return to the top flight threatening the Hoops’ dominance.
Mark Warburton’s side are determined to come back and make their mark and Celtic will need to be at their best throughout to ensure it is their name on the trophy once again.
