Esher coach Mike Schmid says the Surrey club must not lose focus after boosting their chances of surviving relegation.
Beating Plymouth last Saturday means Esher can stay in the Championship if they secure a bonus point (four try) win at London Scottish.
Schmid told BBC Surrey: "It's an exciting prospect that a little bit of our future is in our hands.
"We've got to go there with an attacking game plan. But we can't disrespect our opponents."
He continued: "We can't give them any points out of the game and we've got to get the maximum, which keeps us where we are."
Schmid was impressed by his side's performance in their 42-17 win over Plymouth, their first victory in their fifth relegation pool match.
"I'm disappointed we didn't do it in our first four play-off games," he continued.
"We played to our potential, played to our strengths and executed the game-plan perfectly.
"Now we've got to back up our performance. We need make sure our mental game is switched on and we have that edge [against London Scottish].
"We've got to play like it means more to us."
