Celtic can inflict further damage on Rangers' domestic trophy hunt when the sides meet on Sunday. .
With a six- point advantage in the league and the Premier Sports Cup in the bag, ending their rivals' Scottish Cup dream would be a significant blow.
But Ange Postecoglou is without striker Giorgios Giakoumakis and has some important decisions to make.
Aside from the Greek forward, it looks like the Celtic boss has a clean bill of health among his playing squad.
David Turnbull and James Forrest have both had niggles recently but Postecoglou has confirmed they're both fit to tackle Rangers if called upon.
Japanese standout Kyogo Furuhashi is raring to but will he get the start?
Then there's the midfield toss up between Matt O'Riley and Tom Rogic. One of them will be selected alongside captain Callum McGregor and Reo Hatate but it's unlikely both of them will play together.
Speaking at his press conference, Postecoglou said: “Giakoumakis’ prognosis wasn’t too bad. It was nothing serious.
"He’ll probably miss this weekend but we’re confident he’ll be available next week.
“Kyogo trained well and did everything the boys have done. We have options – and we are going to need them.”
Predicted Celtic XI
O'Riley has been in fine form - scoring two goals against St Johnstone a week ago. But Rogic has been round the houses in Old Firm matches and has a sensational scoring record.
Kyogo has been absolutely itching for action since returning from injury but will it come from the start?
