Wasps boss Dai Young says his side know exactly what to expect from Saints at the Ricoh Arena on Sunday.
But he admits trying to stop it will provide a huge test for his players in their final pre-season friendly.
Saints smashed Saracens 36-17 at Allianz Park last Saturday, with the likes of Luther Burrell, who scored twice, and Dylan Hartley playing a key role.
The forward pack put the squeeze on Sarries, with the backs ruthlessly efficient.
And Young said: “We know the challenge we’re up against this Sunday. Saints topped the table in the regular season last time out and are a tried and tested, experienced squad.
“You don’t win Premierships and do as well as they have over the past few seasons without having a strong squad that’s used to playing at the highest level.
“They may have a few internationals on Rugby World Cup duty, but they also still have plenty of internationals within their ranks lining up this weekend.
“We are expecting a massive challenge, particularly up front as normal. Saints have a big scrum and a big driving lineout game and they are very direct around the corner.
“We know what to expect, the challenge, as always, is trying to stop it.
“This final pre-season game will give us a good indication of where we are, as we head into the new season, having played two fixtures against Premiership sides as well as one against Samoa.
“We don’t have to be 100 per cent perfect against Saints this Sunday, but hopefully coming out of the game we will only have one or two things to work on.
“The important thing is to be full of confidence and belief, ready for Harlequins on Friday, October 16, in our first Premiership game of the 2015/16 season.”
