Extra spice will be added by being up against Wasps and Ireland scrum half Eoin Reddan as the pair are both from Munster and grew up playing against each other.
..Murphy's chance in the Leicester starting line-up comes after a knee ligament injury to England scrum half Harry Ellis, he had his first major final at Twickenham in the Premiership last week and is relishing the big-match opportunities.
"Munster won it last year and I was in the overall squad but not in the match day squad so after that it means a lot to me personally to be involved in the final this year," said Murphy.
"I am really looking forward to another big final, a massive occasion obviously and a sell-out crowd at Twickenham. It could be a great way to end our season but obviously we have a job to do and that is what we are concentrating on.
"With Harry playing so well throughout the season it was always going to be difficult to get into the team, but this is what you have got to aim for playing for the Leicester Tigers.
"I think I played OK last week, a bit of a shaky start but it went well from there. The forwards made it easy for me and I really enjoyed it. It is something I want to play more in."
The rivalry with Reddan will give the contest an extra edge for Murphy, though the pair have not spoken in advance of the game.
"We were born in Munster, we are both about the same age so we know each other pretty well - it is a battle I am really looking forward to. We will leave the talking until after the game," said Murphy.
