Manager Ronny Deila admitted that Tom Rogic’s strike was the “best way” for his Celtic side to grab all three points against Kilmarnock.
The Hoops moved four points clear at the top of the Scottish Premiership following Rogic’s stunning long-range effort.
Deila’s side, who still have a game in hand over Aberdeen, were well below their best for the majority of the game but they still prevailed 1-0 against Killie.
A lack of chances were apparent for both teams but Deila was elated after the final whistle and he admitted that Rogic’s goal was a worthy way of winning the game.
He said: “With a goal like that, it is the best way to win sometimes. We didn’t play well but we kept fighting, and the fans were unbelievable. That is a moment we are going to remember for a long time.
“We didn’t play well at all today but sometimes you just have to carry the points away with you and that is what we did. That is the most important thing.
“We were more passive and didn’t get up to tempo with our passing. We were struggling with the surface, which is not an excuse, but it is something we have to work on.”
Saturday’s win was marred by an injury to left-back Kieran Tierney who had to be taken off due to an ankle knock.
The problem could see him miss Scotland’s friendly against Denmark on March 29 although Deila has yet to rule him out.
“We will have to see tomorrow [Sunday]. I don’t think it’s a very big one,” he added. “Hopefully he will reach the national team but he has to be 100 per cent.”
