The big things we learned last night are that Patterson has not improved at all and Gilmour is critical for us holding our shape and being able to control the middle, when he left the midfield it was a shambles.
I think had McKenna not withdrawn he would have come on for Tierney, more comfortable as left CB though that doesn't really explain why Souttar was so bad.
I'd also give Shankland another start on Tuesday.
