25-yr-old must start v PSG: Three things we learned from emphatic Celtic win at Hamilton

Celtic need to pick a shape and stick with it

Celtic played an unfamiliar 3-4-3 against Hamilton and while they never needed to get out of first gear to see off Martin Canning’s side, better teams will exploit the gaps left.

Kieran Tierney has all the potential to go on and be a fantastic full-back but moving him around on a regular basis won’t help his development.

Similar applies with Kris Ajer; the young Norwegian could have started in a shape similar to the one Celtic will use against PSG but Rodgers opted to experiment instead.
