Speaking after the game, Blues prop Gethin Jenkins admitted: "It was a great win for us, the boys really put the effort in.
"We knew we had to come out here and put a good performance in to get our European spot, it's a step closer and I'm really chuffed with the win.
"A few early tries and some good defence throughout the game really helped us."
