Paul Hartley has urged his Cove Rangers side to continue being ruthless at home to maintain the 100% record.
The League 2 leaders have yet to drop a point at Balmoral Stadium since joining the SPFL in the summer.
You have to go back to the Betfred Cup game against Dundee, in which they took the Championship outfit to penalties, to find the last time the Aberdeen side failed to pick up all three points on home soil.
This win over Brechin City, which came courtesy of second-half goals from Mitch Megginson, Declan Glass and Scott Ross, ensured Cove maintained a five-point gap at the top of the division.
Hartley, who took over as manager in the summer, wants no let-up from his in-form charges.
He said: “We’ve got to keep it going. We’ve got to be ruthless.
“If we can win in style, brilliant. We’re consistent and in a good run of form but there’s a long way to go. We say to them every week that teams are going to sit in, be compact, have bodies behind the ball and frustrate you.
“We need to keep playing and keep working. We want to keep the ball moving and we’ve got some good players. Declan Glass was really good at times. We know he can create something from nothing. He scores a brilliant goal out of nothing off his weaker foot.
“Away keepers are performing really well to keep the scoreline down.”
At times it looked like it would not be Cove’s day, with visiting goalkeeper Ross Sinclair in inspired form.
He kept out Fraser Fyvie, Fraser Aird, Glass and Connor Scully in the first period as Brechin struggled to cling on.
The breakthrough came with 12 minutes to go as Fyvie slipped in substitute Martin Scott and he laid it off to Megginson, who crashed beyond Sinclair from eight yards.
After Brechin’s defences were finally breached Cove upped a gear, with Glass marking a standout display with a well-taken goal from the edge of the box before his corner picked out Ross to head home a late third.
Hartley added: “We had all the play and the possession. We had a lot of chances – something like 18 chances in the first half. We weren’t clinical enough and we were a bit loose today. We were slack with our passing at times but credit to the players – they were persistent and kept going.
“We had to make a change and went two up. We’re going to face this most home games where teams are going to have a low block against us and be hard to break down.
“They had a good gameplan and stuck to it pretty well. But we were persistent and patient.”
