Leicester Tigers director of rugby Richard Cockerill has told his squad to make sure a referee's decision does not cost them the chance to retain their Aviva Premiership title later this month.
Officials have been centre-stage recently as controversy surrounding the perceived over-use of the TMO referral system has raised its head.
With more and more on the line as the domestic and European season enters the finals stages, any decision by an under-pressure referee could decide the destination of a trophy.
Cockerill said he has been "working a lot" with referees and their bosses in recent weeks, and that it is up to his team to make sure they are ahead in games so the odd decision cannot change the outcome.
The Leicester boss has not been shy of a run-in with referees in the past, and he admits their job is getting harder and harder.
"I was critical of our side after the defeat at Harlequins," he said. "I felt that we were waiting for the referee to make calls our way.
"Referees will make mistakes because it is a hard job to do and we cannot simply wait for them to give us a call when we think we are in the right.
"I have been working a lot with Brian Campsall (Elite Referee Development manager at the Rugby Football Union) and Tony Spreadbury (former international referee) during the past few weeks, and it is getting hard for referees.
"There is the TMO and replays and all sorts of regulations brought in at the last minute for them to deal with this season.
"If we can be as good as we possibly can be, the odd error or mistake that the referee could make might not be the deciding factor in any game we are playing in.
"That is what we have to concentrate on for the rest of the season.
"That is what, at last, I have decided to concentrate on too."
