Teams from the Aviva Premiership completed a clean sweep in the Champions Cup for the first time since 2008 as Wasps finished off a perfect weekend for English sides.
Dai Young’s team produced a stunning 32-6 win over three-time champions Toulon, making it nine points from a possible ten in Pool 5 as they put themselves in great position to make the last eight.
Two tries from Nathan Hughes, along with scores from Ruaridh Jackson and Frank Halai set them on their way to maximum points at the Ricoh Arena.
"I could not be prouder of the players, I thought they were excellent," said Young.
"There were a lot of questions before the game, was last week a one off? Could we back it up? Was it a case of Leinster being poor or us being good?
"We've shown everyone we are a quality team. We've still got things to improve on but that was close to as good as it gets."
On Saturday Northampton had beaten Pro12 champions Glasgow Warriors 26-15, coping with the sin-binning of Luther Burrell to pick up a valuable win away from home.
Ahsee Tuala scored two tries while George Pisi also crossed and director of rugby Jim Mallinder was delighted with the effort of his defence.
"The way the 14 on the pitch organised our defence thereafter was crucial to our win," he said.
"I was very pleased with how we defended. We kept them out – well mostly."
Leicester were far too strong away to Treviso, and have ten points from two games so far ahead of their doubleheader against Munster in December.
Bath Rugby were also victorious on Saturday, thanks to George Ford’s late penalty, which saw off the challenge of Leinster 19-16.
A dominant performance from their pack set them up nicely before Ford held his nerve in the closing stages after Johnny Sexton had missed a chance to put Leinster in front.
"You understand what type of kick it is to take a lead with a few minutes to go,” said Ford.
"But you just focus on the process. You are in your own little bubble as a goal-kicker, you try and block everything out and just hit the ball like you do hundreds of time in training.
"We didn't score many tries today, but we were positive in the way we went about things."
In the final game on Saturday, Exeter picked up all five points against Bordeaux-Bègles in an entertaining encounter at Sandy Park, winning 34-19.
Olly Woodburn scored his first two tries for the club, while Moray Low and Ian Whitten also crossed for them in an impressive display.
On Friday night Saracens had got things going with a 27-6 win at Ulster, picking up all five points thanks to a late try from Billy Vunipola.
