Leicester fly-half Toby Flood says a run of "Test match" quality games is ideal preparation for Sunday's Heineken Cup tie against Clermont Auvergne.
"Coming off was one of the most tired I have ever felt," the England back told BBC East Midlands Today.
"If it's not a Test match-type game you could be a bit undercooked. But it puts us in a good place."
Tigers now face back-to-back Heineken Cup fixtures against a formidable French side. And Flood says that they will take great confidence from the thrilling victory over Saints.
"To come through that gives you the real boost you want," he said. "After a win like that, the feeling in the camp is good and the boys are positive going to France.
"We know how difficult it is and we know we have to be on our game and have to be precise but we go into the game with confidence.
"If you go into a game thinking you cannot win then don't turn up.
"We will have a tough game but so will they."
