Although, McCall was very disappointed with conceding the second goal from a corner as Ambrose headed home unchallenged to open the floodgates.
McCall added: "We won't be up against a side like that many times this season. That's probably as strong as they can be.
"When you play Celtic, we need to be at our best and they need to be under it. It was vice-versa. We were under our best form and they were certainly at the top of their game."
Meanwhile, McCall explained why he had to come on to the park after the half-time whistle and haul an angry Keith Lasley off as his skipper continued to protest to referee Steven McLean after being booked in the aftermath of the opening goal.
"It was his booking," McCall said. "He got booked for something he said and Las says he never said it whatsoever. That's what he was upset about."
