David Young knows his side did the business in Italy after the regions biggest ever win in European competition.
Young's troops notched eight tries, including six in a second scoring spreee to put Italian champions Calvisano to the sword at Centro Sportivo San Michele.
He said: "The first half was tight. We wasted a few half chances early on and lost our way a bit before half-time, trying to play to much rugby in the wrong parts of the field.
"But we recovered and controlled the second half and scored some great tries. I was also pleased we didn't concede a late try when they finished the game so close to our line. This pool is going to be very tough and potentially every point could count, so we didn't want to give away any soft tries at the end.
"I couldn't really have asked for more and I would certainly have settled for that before coming out here. It was a game we had to win and we also targeted a bonus point, so I'm delighted that we've done both."
