Saints came out on top after a 32-10 victory in a home sell out at the Totally Wicked Stadium after a double from Makinson was added to by tries from Coote, Naiqama and Lomax.
And Morgan was naturally delighted with the victory.
Morgan said: “It was a good performance from the boys, it’s always good to get one over on the rivals, it’s great for us, and the the fans and the club as a whole.”
Saints moved 10 points clear with the victory as Warrington fell to defeat against Salford, but Knowles insists, Saints won’t lose focus.
“We won’t get carried away with tonight, we have another tough game next week down in London where we got beat last time there so we will have a couple of days off, rest up and fix our minds on London.”
