Ange Postecoglou is set to put his Celtic theory about being unafraid to change a winning team to the test against Dundee United.
He has some big selection decisions to make ahead of the corking Scottish Cup quarter final clash at Tannadice.
David Turnbull is back in training but the clash at Tannadice is likely to come to early for the attacking midfielder.
Celtic were dominant against Livingston but Postecoglou stressed during a recent interview that he doesn't believe sticking with the same same team yields better results.
And that could come into his thinking with the likes of Josip Juranovic, Giorgos Giakoumakis and Reo Hatate eyeing a start.
Daizen Maeda is also set for a payoff for his non-stop hard work against a side who won't sit in for 90 minutes.
Celtic were rampant in December during the 3-0 win over United on a day Kyogo didn't stop from first minute to last.

Predicted Celtic XI
Celtic have multiple options but a return for Hatate could make sense and allow Callum McGregor to drop into the deepest midfield role. The Japanese star has been leggy of late but is expected to catch fire again.
