The 26-year-old is expected to make his first league appearance in 10 months at The Rec following ongoing shoulder injuries, although he returned in the LV= Cup against Exeter Chiefs two weeks ago.
"We are not under any sort of illusion that eighth is good enough. We want to be competing at the top end of the table," Webber told BBC Sport.
"I'm looking forward to getting out there on a Saturday at The Rec. I know I've got a long way to go to get back to the standard that the club expect of me and I expect of myself.
"If you're injured it's a bit like turning up at work and not being able to do your job, so it's great to finally be able to contribute."
Webber tore a muscle in his shoulder playing for England in the Six Nations last year.
