Celtic hero Gary Hooper has hailed the club's mental strength after avenging their home defeat to Rangers with a convincing success on Sunday.
Neil Lennon's troops suffered a 3-1 defeat to Rangers back in October after summer signing Hooper gave the Bhoys the lead on the stroke of half-time.
Celtic claimed a 2-2 draw with Gers in their Scottish Cup clash earlier this month and took a grip on the SPL title race at the weekend with a 3-0 success over their arch-rivals.
Hooper helped himself to a first-half brace and, while the club's personnel has not changed much since their October shocker, he thinks the side have become a lot more resilient mentally.
"We showed with this performance that our mental strength is really good, we are performing well and everybody is comfortable on the ball," explained Hooper.
"Maybe we are just more confident. Not much has changed so maybe we just believe in ourselves more now.
"We are performing well and we have shown that for the last few months.
"It was a perfect result and the performance was too," he continued. "We kept a clean sheet and scored goals and that's what we need to do.
"There is confidence everywhere. We showed that by just keeping the ball when we were 3-0 up and we didn't really give them much and we performed well.
"The manager told us to enjoy it and, basically, win. He didn't want anything less and we showed that.
"There was nothing to fear. We have been performing well and defending well and that's the main thing.
"We scored goals and kept Rangers out and I managed to get two goals myself and Kris got one with a good strike."
