Wales star Williams helped Warren Gatland’s side to an historic 2019 Guinness Six Nations Grand Slam earlier this year while he also sealed Heineken Champions Cup success with Saracens.
Against the Chiefs the full-back or wing made it a hat-trick of trophies this season as he scored a stunning try from an Owen Farrell cross kick in a dramatic 37-34 success.
Williams’ Wales team-mate Tomas Francis was joined by Alex Cuthbert in the Chiefs side.
