England trio Luke Cowan-Dickie, Don Armand and Henry Slade have a well-earned week off
The Chiefs welcome Worcester Warriors to Sandy Park in tomorrow's Gallagher Premiership clash.
Positioned second in the table, it's been Exeter's best-ever start to a top-flight season. That said, head coach Hepher believes his side have much more to come.
Speaking to the clubs website, he said: "Obviously we're delighted to have won the opening four games, but at the same time we're still looking for a pick-up in performance. If we're being honest, the last few weeks in terms of performance have not been as great as we would have liked, so we've had to look at certain areas and aspects of our game.
"Certainly, we'd like to up our intensity in both attack and defence which, if we do that, then we can return to the quality performances we've already had this season."
