"We're bitterly disappointed with how we played but fortunately it remains in our own hands now," the scrum-half told SaintsTV. "We've got to go down to Exeter against a good team and really front up."
Dickson also admitted that the performance on Saturday was far from what the fans and the squad themselves have come to expect, promising they will do everything in their power to get it right in a must win clash at Sandy Park.
"We'll make sure that next week will be a completely different story. We'll make sure we put right the things that didn't go well and really put on a show for the fans that come down to Exeter with us.
"Any player at this club wants to win things and wants to be in that semi-final. Nothing else is acceptable and now it's up to us to get a win next weekend and then beat Worcester."
