And Copeland was thrilled to keep the European dream alive and praised another massive defensive effort from his team-mates.
He said: "We set goals for ourselves and the big one was to get a result. It puts us in a great position to go forward from the group and into the next round.
"The attitude was fantastic. Everyone was jeering each other up and passionate about it.
"We fought and fought for it. The pack were outstanding, it was a real dogfight and I'm delighted to come out on the right side of it.
"Chief (Dale McIntosh) has brought this defensive work in and you are playing for the guys next to you. You have to work your socks off. You do it for each other when you are out there, you don't want to let anyone down.
"If we do make mistakes then there is always someone there to put their back in and look after their mate. It's working for us and to keep them down to one score is great credit to the boys.
"We are top of the pool and there is a lot left in this season before I move away," added Copeland, who this week confirmed he will join Munster from next season.
"I love the fans at Blues; they have given me such great support personally as well as the team.
"I really want to do it for them and the region. I want to leave something behind and make a legacy. I will try my best to do that and things are going alright at the moment."
