Cornish Pirates head coach Ian Davies rued a missed opportunity after seeing his side beat Swansea 27-9 in the British and Irish Cup yesterday.
Pirates remain top of Pool Three but their hopes of being one of the top four qualifiers into the knock-out stages suffered a setback as they failed to win the four-try bonus point.
Davies felt his side lacked the required accuracy in their game.
He said: "We kept putting the ball to the ground. Our passing was poor, we ran into touch, we knocked on, we gave far too many penalties away and that allowed Swansea to come away without receiving the beating they should have from us.
"We certainly had a lot of possession but we made life hard for ourselves with those errors. The longer and bigger picture is that it could make life really hard for us.
"Instead of sitting on top of the table with three wins and three bonus points, we are now only four points ahead of Carmarthen Quins.
"We need to be one of the top-four qualifiers to get a home quarter final. We are still in there at the moment but we missed a great opportunity to get a bonus point."
Pirates face three more games in the group stage. However, two of those fixtures are away from home, against Swansea this weekend and then Carmarthen Quins.
Davies said: "It puts pressure on us to get a bonus point in Swansea or at Carmarthen – those are two tough places to go.
"We will have to make sure we are accurate in what we do and that will have to be our buzz word. Swansea will be a different team at home compared to what they were here.
"Most of their games are fairly local, so this was a long journey for them. They will be buoyed by the fact they stayed with us for long periods.
"We have to be accurate in what we do and bring an intensity that we didn't show this time."
Pirates only took control after the introduction of replacements Gavin Cattle, Laurie McGlone and Alan Paver in the second half.
However, Davies praised skipper Kyle Marriott for his 70-minute performance on his return from a hamstring injury.
He said: "The big plus point for us was Kyle Marriott coming back. It was great to see him and, hopefully, he can get a bit longer next week. We want to get a full game out of him so he is fully back onboard."
