After an insipid first-half, Celtic made one change by bringing Haissem Hassan on for Sebastian Tounekti. The manager admits it could have been more.
He said: "It could have changed. Me personally, I think young Colby has come out of this with great credit. I think he's an absolute warrior.
"Sometimes we misplace passes, but he's got a big heart. I think we can all learn from that. And because of the size of his heart, he was booked in the first half, but he kept going right to the end.
"He was booked against St Mirren after about eight or nine minutes, still kept going. In terms of heart and desire, he's been a big plus for us."
