There are just two changes on the bench with former All Black Ross Filipo in line for his first appearance for the club, while Joe Burton comes in for the injured Billy Vunipola.
Young said: "To get off to a winning start was exactly what we needed but we're going to have to step up again this weekend.
"There was a lot to be pleased with last week but we've certainly not been patting ourselves on the back because the thought of playing a quality side like Leicester next was a pretty sobering one.
"To have them come here on the back of a loss will probably make them even more dangerous. They are a side I have a lot of respect for and we can't afford to give them any opportunities because they will take them."
Leicester were shocked at home by Exeter in their opening fixture and director of rugby Richard Cockerill makes two changes to the starting line-up.
Mathew Tait - a late withdrawal last week with injury - and Ben Woods come into the back row, with Julian Salvi switching to No 8.
Thomas Waldrom, who suffered a groin injury in the closing stages of the defeat by Exeter, is named among the replacements.
Graham Kitchener is back to full fitness after injury and the lock joins the matchday squad for the first time since his summer move from Worcester. Fly-half Jeremy Staunton is also included on his return from injury.
"I thought we played some pretty good stuff in parts against Exeter last week but we made some costly errors," said Cockerill, whose squad has been weakened more than most by World Cup call-ups.
"We knew this period was not going to be easy and we just have to battle through it."
