The Rovers' captain knows that after Wednesday's loss to Bolton that they have to show a reaction and Sunday's game gives the players the perfect opportunity to do so.
"The bad performance against Bolton is something we want to forget, put to bed and make amends for," Murphy told Rovers Player
"It wasn't acceptable so we owe the fans one for that and Sunday is a big opportunity to do that.
"Obviously I've not been involved before but it is a game I've heard a lot about so I'm really looking forward to the big derby and the atmosphere it brings.
"These are the type of games we love playing in, you start feeling the buzz, everyone is talking about the game.
"For me personally and for the rest of the team it would be a huge boost and a thank you to the supporters for sticking with us.
"In terms of what the game means to the Blackburn supporters and the people in the area, it is a massively important thing.
"They deserve some happiness and beating your local rivals always makes you happy."
A veteran of countless clashes between local rivals, Murphy knows that remaining cool under the white-hot atmosphere of a derby is essential.
"We all have to embrace the atmosphere, we need a positive result," added Murphy. "We need to overcome that atmosphere and intensity and play with a calmness and matureness that you would in a normal game. It is important to not let the occasion get the better of you.
"I remember over the years the Merseyside derbies we had a fantastic record and that was mainly because we kept 11 men on the pitch in most games.
"The discipline on the pitch is going to be important, the tactical awareness to not let the intensity of the day carry you away.
"I think after losing to Bolton we know that we all let ourselves and the fans down in that game.
"So if we can get a positive result on Sunday then at least the fans can forget about Bolton more quickly than they would have done.
"We need to start putting results together, we don't want to find ourselves way off the top six come January."
