However, his focus is now on unbeaten Warriors as he echoes the call of Head Coach Richard Hill for the team to hit their straps after several games when the Sixways side has only shown glimpses of top form.
"Moseley really are a great club with great tradition so I am looking forward to going back," said Williams.
"It is a very difficult place for us to go and get a victory - it will be a tough game. They have players like Gareth Taylor at nine who was a good influence on me when I was there. He is a Moseley lad who knows how to play the conditions at Billesley Common.
"But, at the end of the day, it is only a patch of grass and we have got to go there and look to play for 80 minutes. That is something we have got to do because we haven't so far this year. If we can put together a full performance we have got to be confident.
"Moseley have a very experienced pack with Terry Sigley and Nathan Williams, they are very good scrummagers," he added.
"The coach Ian Smith has got a very well drilled pack together and a very solid back division, not to mention some strike power on the wings with Nathan Bressington. We have got to go there, be enthusiastic and match their pack and take them on."
Warriors go into the game boosted by the return of fit again back row Pat Sanderson while Spanish wing Oriol Ripol will make his first league start of the campaign.
"Both are class players and we are excited to see them come in, plus the likes of Balders (Adam Balding) on the bench, there is class throughout the side," said Williams.
"Pat will be very enthusiastic and he has certainly been very vocal in training. Oriol is very exciting when he has the ball.
"To have players like that come into the team is very beneficial and everyone has got to up their game to stay in the side."
