Having got their Aviva Premiership campaign off to a winning start with victory over Newcastle last week, forwards coach Martin Haag is keen to maintain the momentum at the Rec.
"We're preparing for Saracens this week in the same way that we prepared for Newcastle last week, but we know it's going to be a sterner test. They are the present champions and have competed brilliantly with Leicester over the last two years. It's a big test for us and one we are looking forward to," said Haag.
"It's our first game in front of our home crowd. I expect the crowd to be in good voice and confident, and we'll be the same. We've got a chance to play one of the teams that turned us over at home last season and we need to make sure we do a job and come away with a win."
