Williams hopes for spot in last eight
The Irish province ran in eight tries to end their Pool One campaign on a high as Rob Herring, Darren Cave, Rory Scholes, Sean Reidy, Craig Gilroy, Robbie Diack, Ian Humphreys and Jared Payne all crossed the whitewash, with Humphreys and Paddy Jackson adding all eight conversions between them.
The win moves Ulster into the quarterfinal places but they now have to sit and wait while the remaining pools are completed before discovering if their superb performances has been enough to seal a knock-out place.
But No.8 Williams, who will join Cardiff Blues next season, hopes they have done enough to ensure this will not be his final European appearance in Ulster colours.
"We knew we needed to do a job today and make sure all the pressure goes on to the other sides who are also trying to get out of the pool stage," Williams to EPC Rugby.
"We knew playing first would give us an advantage of sorts because we were not chasing any particular score, we knew a bonus-point win would give us a chance and now it is down to the other sides.
"Hopefully this result has created a bit of pressure for them, they have to get the results they need and it was a superb performance from our lads and we could not have done too much more.
"We'll spend a bit of time together this afternoon and then I would imagine we will be heading home to sit on th sofa and see how things turn out."
