We could have scored more - Rodgers
Manager Brendan Rodgers felt his side should probably have scored even more goals against St Johnstone.
As it was the champions were forced to settle for a 4-1 victory courtesy of Patrick Roberts (2), Dedryck Boyata and substitute Callum McGregor following a blank opening half at Celtic Park.
"It was a really exciting performance for the supporters and a joy to watch the team play to that level," Rodgers told BBC Scotland. "We were very good for the first 35 minutes without getting the goal, but we started the second half really well, and just switched off for some reason to concede the goal.
"But our response was spectacular," he added. "We scored four goals, and maybe could have finished with six or seven if we had been more clinical."
