Worcester Warriors return to Adams Park in the LV= Cup on Sunday hoping to avenge last month's narrow Premiership defeat by Wasps.
Assistant coach Nigel Redman says that as well as gaining revenge, the Pool Two leaders also hope to build on their opening win against Scarlets.
"We want to secure a second win to stay at the top of the group," he told BBC Hereford & Worcester.
"We have played Wasps in the league. It will be different in the cup."
He added: "It gives them a chance to play their squad players and it gives us a chance to play our players who are pressing for positions, those who want to put our first-choice players under pressure.
"We can mix and match the players to help the younger players like James Currie, who played well against Scarlets, and Ben Howard and Andy Short. It gives them the opportunity to play with more experienced players on a bigger stage."
Summer signing Rob O'Donnell makes his first start at prop following his move from Rotherham Titans.
He is part of a new-look front row alongside Ceri Jones and Ollie Hayes.
Veteran Craig Gillies is back in at lock alongside captain Dean Schofield, while Errie Claassens returns at full-back.
Worcester began this season's LV= Cup campaign last Saturday with a 34-18 win over Scarlets at Sixways.
