Exeter boss Rob Baxter says his side must pick up try bonus points after their 30-16 LV= Cup win at Wasps.
Dave Ewers, Aly Muldowney and Myles Dorrian all scored for the Chiefs, with Gareth Steenson kicking 15 points, but the vital fourth try eluded them.
Exeter are one point off Northampton at the top of pool four, a point Baxter felt his side should have claimed.
"The bonus point was there for us to go after but we didn't go after it very well," he told BBC Radio Devon.
"We still have to learn how to chase down bonus points, and maybe it's our fault that's how we talk about 'chasing' them and it's really about continuing what's working well for you.
"If you score three tries with 25 minutes of the game left you should just be able to roll on through and keep yourself going and get that last try.
"We almost worked too hard for it and we started playing in an incorrect manner for the game," he added.
But Baxter, who greatly changed his team for the clash at Adams Park, was happy with how his side coped.
"We've changed the side and they showed great physical endeavour out there. They went after the game and they've won the game so I'm not going to be too critical.
"If there was one thing that stood out for me today it was the hunger in our defence was absolutely outstanding both in our line speed, the way we chased down the ball carrier, and our work in the ruck as well.
"If we came here in the Premiership and won 30-16 we'd be fantastically happy and that's sometimes what you've got to remember," he added.
