Celtic manager Brendan Rodgers was in full praise of his side following their five goal demolition of St. Johnstone.
A hat-trick from Scott Sinclair as well as goals from Scott Brown and James Forrest ensured a big margin of victory for the Hoops, who progress to the next round of the Scottish Cup.
The Saints have been one of the better defensive sides in Scotland this season, keeping eleven clean sheets in the league thus far, but were unable to tame a rampant Celtic attack.
After the game Rodgers was not pleased with every aspect of their performance, but was happy with their half-time adjustments.
“I thought the first 20 minutes were very good. We were quick in our passing, created chances and got the first goal.
“That was important, particularly against St Johnstone who defend so well and will come after you a little bit more. Scott Brown got his trademark goal every five years! It was a great strike, and wonderful technique.
“I thought after that we got a bit sloppy, with some misplaced passes, and we came out of our shape. Then we gave them an opportunity and Scott Bain had a good save. At half-time we had to re-establish ourselves and control of the game in terms of our positioning.
“That allows us to press the game better, and sustain more attacks. In the second-half we were excellent. It was a very good performance and we’re through to the next round.”
