Celtic boss Neil Lennon praised the character and resilience of his side as they came out on top against Aberdeen despite being drawn into a battle with both the Dons and the remnants of Storm Dennis.
At a windswept Pittodrie, the visitors took the lead through Callum McGregor after 10 minutes, but were pegged back before half-time thanks to Ash Taylor's composed finish.
It looked like a share of the spoils was on the cards before Kristoffer Ajer coolly netted an 81st-minute winner for Lennon's side.
The Northern Irishman said: "I'm thrilled. It's a massive win in treacherously difficult conditions to play football. All credit to the players who dug out a marvellous result for us.
"You can't always play slick, quick football and we had to grind it out today. We didn't want to drop points obviously, but it was perhaps looking like we would. A point a Pittodrie is sometimes a decent result and in these conditions the game could have gone either way.
"We've a bit of character and resilience. We're not getting ahead of ourselves, there's a lot of football yet to play but in the context of the run that we're on it's a big win."
Steven Gerrard criticised referee Euan Anderson and his team of officials after Rangers narrowly beat Livingston 1-0 at Ibrox.
In a fixture that was postponed on Saturday due to a waterlogged pitch, midfielder Scott Arfield scored with a drive in the 59th minute with striker Alfredo Morelos and substitute Florian Kamberi subsequently having the ball in the net only to be ruled offside.
The Light Blues boss, whose side went back to being 10 points behind Celtic, with a game in hand, claimed Morelos's strike at 1-0 should have stood and that his team should have had a penalty in the second half for an apparent handball by Livi defender Ciaron Brown to stop Rangers defender Connor Goldson getting on the end of a corner.
Gerrard said: "We aren't firing on all cylinders at the minute so it is important that you get the over the line and we did that today but we could have done it more convincingly.
"Disappointed in the officials today, I must say."
