Celtic manager Martin O'Neill has compared his side's spirit to the title-winning team of his first spell in charge of the Glasgow side.
"The spirit the players has been absolutely fantastic," he said of their win in Kilmarnock after being 2-0 down.
"I managed, coached, a really top quality side here 20-odd years ago who had loads of spirit, loads of resilience, loads of ability.
"And these lads here are emulating that in many aspects and sometimes surpassing.
"It was a wonderful second-half performance for us.
"I thought we were very poor in the first half. As a team defending, we weren't that good then we keep giving the ball away at times, but the second half was totally different.
"We made the changes at half time and then Seb scores a wonder goal for us and puts us right back in the game, culminating in us winning the match.
"Kilmarnock adapted to the conditions, the rain, the pitch, much better than we did and sometimes you just have to dig in - and that's exactly what we did.
"You can't keep doing that. We've got to put in the full 90 minutes."
