EDINBURGH trashed Russians Krasny Yar Krasnoyarsk 78-0 at Murrayfield to also make it four straight wins.
The Scots ran in some 10 tries and Blair Kinghorn kicked five conversions during the first half.
Assistant coach Roddy Grant said: “It’s quite difficult at half-time to be that far up and it was just pleasing the guys came out and played in the second half like they did in the first.
“Probably the most pleasing thing is nilling them. We conceded two tries [to Krasny Yar] in Russia which was frustrating.
“The big focus really was getting a result in terms of the points out of the game - getting five points hugely helps us going forward.
“We’ve tried to attack when we can and with the amount of tries we’ve scored it has been good or better. The style [Richard Cockerill] is driving seems to have been working for us, but we’re really happy with where it’s going.”
Elsewhere, Worcester’s hope of progress into the last eight suffered a blow with a 27-20 defeat at Oyonnax, who recorded a first victory in Pool Five.
The Warriors could have moved above leaders Connacht, who will be out to extend a 100% record at home against Brive on Saturday.
It was, though, the home side who produced the required performance on a freezing, snowy night in eastern France.
Julien Audy added a try to his two penalties and conversions as Oyonnax opened up a 20-3 lead at half-time on the artificial pitch.
Despite a second-half fightback with scores for Sam Olver and Alafoti Faosiliva, which secured a bonus point, it was not enough as the Top 14 side closed out a first win.
Newcastle edged out the Dragons to maintain their 100% Challenge Cup record and cement top spot in Pool One with a 27-25 win at Rodney Parade.
Newcastle led 24-17 at half-time after a penalty from Joel Hodgson and a converted try by Gary Graham.
Bordeaux Begles beat Enisey 36-27 to move above the Dragons into second place.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
