The Exeter Chiefs have made a terrific start the the Premiership rugby season but face an acid test of their credentials as league leaders Saracens visit Sandy Park.
The Londoners may well be buoyed by the return of their England stars from international duty but the Chiefs will look to last season's home victory against Saracens as proof that England's current top team is beatable.

We do expect it to be another physical game but they've got some guys in their squad who are obviously England internationals or internationals of other sides, who are top quality players and that's who we want to be challenging ourselves against.
