The sides last met in a notoriously defensive game in the 2011 All-Ireland semi-final, which Dublin edged past Donegal by 0-8 to 0-6.
Both teams have evolved since then, winning the last three All-Ireland titles between them with Dublin’s potent attack widely expected to shoot them to back-to-back crowns.
Murphy conceded: “Dublin have serious firepower and the lads that come in off the bench are also contributing massively”.
“But we’ve lads that are coming in and also doing a great job. We’ve a number of new additions this term that are really coming to the fore.
“Dublin are a more experienced and a better rounded side than in 201 - but I think we’re a better side now as well.
“That was our first season under Jim and, four years down the line, you’d like to think you’re in a better position.
“The experiences we’ve had now means we’re better equipped to deal with what ever situation arises in any given game.”
