Keates, who admitted to being frustrated as the travelling Posh enjoyed plenty of luck as they held on against a wave of Saddlers attacks to take a share of the spoils, wants his team to harness that frustration and take it out on the managerless Pirates this afternoon.
Speaking via the Express & Star, Dean said; "After Peterborough, we were talking about a point that should have been three. But I’ve told the lads to bottle that frustration. If we beat Bristol Rovers it becomes a good point. We have to go again.
"You look at it – Peterborough are slap bang in the middle of the play-offs, they are expected to challenge. But we have limited them to two chances. It was us playing on the front foot.
"Of course we were disappointed not to win with the chances we created. But it is a good point if we get three points against Bristol Rovers."
Rovers, who are currently led by caretaker boss Graham Coughlan, arrive at the Banks's sitting in the League One relegation zone, but saw a run of five straight league defeats come to an end as they defeated Joey Barton's Fleetwood Town on Saturday afternoon.
Keates, who is still looking to secure safety before considering other possibilities, admitted that Rovers will provide a test, he continued; "It’s going to be a difficult game. The manager has openly said he is looking for the job down there. And their players have got to perform.
"They need to impress him, a new manager if someone else does come in and they are playing for their own futures. They are playing for another contract at Bristol Rovers or elsewhere. All those things will be going through their minds."
