Exeter head coach Rob Baxter says his side's defence must improve after they conceded six tries against Gloucester in their first pre-season game.
The Chiefs, who ran in five tries themselves, beat Gloucester 41-38 in their opening friendly fixture.
"If we want to talk about being a top-six side on a regular basis, those teams don't concede 38 points and don't concede soft tries like we conceded.
"We've got to get that out of our system completely," Baxter said.
Exeter conceded three tries in the final few minutes in their first game in the Westcountry Challenge Cup.
"We've got to set ourselves very high standards now, it isn't our first or second year in the Premiership," Baxter told BBC Radio Devon.
"We have to set ourselves extremely high standards if we want to be driving into that top six and it's my job to make sure we face up to those facts.
"In some ways from a coaching perspective having a few moans and a few gripes to hit the players with is probably a good thing.
"If we hadn't conceded those late tries and we'd won by 40-odd points to 20, it might have all felt a bit too comfortable and that's what you don't want at this time of year."
