Ronny Deila is hoping that beating in-form Partick Thistle despite being down to 10 men will spark Celtic into life.
Leigh Griffiths' late strike secured the reigning champions' first home win in five games.
"It was such an important result," said manager Deila. "It showed very good team spirit that we stay in the game when we have 10 men and we created a lot of chances in that period as well.
"The way we did that will give a boost of energy for the next games."
Deila praised Griffiths, who was returning from injury, for helping spark Celtic into life after midfielder Nir Bitton was sent off for a second yellow card.
"Partick Thistle tried to keep possession and keep us under pressure and it was important to have speed up front and he and James Forrest made a difference when they came on," he told BBC Scotland.
"I am also happy that Stefan Johansen is starting to look like the player he was last season."
Celtic goalkeeper Craig Gordon denied Thistle on a couple of occasions and the visitors also had an effort cleared off the line before substitute Griffiths found the net.
"We were very relieved but very happy as well that we turned this around," said Deila.
"We looked a little bit anxious. To be fair, Partick Thistle did well as well and we had to work hard for winning balls and interceptions.
"There was too much playing in our back four instead of getting it up to the midfield and feed the wingers.
"There's a lot of things to improve, but it's small details to get it right and to get three points was an important thing."
While Celtic's win extended their lead at the top of the table over Aberdeen to three points, it denied Thistle a second straight away draw with the top two sides within a week.
Thistle manager Alan Archibald is determined that a first defeat is seven games will not halt their recent improvement.
"We put a lot into the game and it's a hard one to take," he said.
"We've defended stoutly during a great run. But to be fair, Celtic are champions for a reason.
"They keep on going with that pace and quality and got their goal.
"The lads are gutted, but we need to make sure that we apply ourselves in the same way we did in this game and take it into the St Mirren game in the Scottish Cup and the Dundee one in the league."
Archibald thought Bitton's red card had knocked Thistle out of their stride.
"We had a good shape about us, a rhythm to our game and everybody knew their jobs and looked dangerous on the break," he said.
"It upset our rhythm Celtic getting a man sent off, but even then we looked a threat."
