Kevin McStay has rubbished suggestions that Dublin might race into a big lead against Kerry when the sides collide in the All-Ireland final, saying that any such talk is "complete nonsense."

Dublin are seeking a historic fifth All-Ireland crown on the bounce this weekend having effectively cruised through much of the championship campaign. Mayo gave them a scare in the semi-final with an impressive first-half display which left Jim Gavin's side trailing by two points at the break.

But Dublin exploded to life after the restart and crushed their Connacht opponents to book their place in the decider where they will take on their familiar foes from the south.

"They really got themselves into the final brilliantly," said McStay on RTÉ's Saturday Sport.

"You have to salute their management and the team themselves. No fuss, they did what it says on the tin.

"They haven't let the hype take off, so they're in great shape for it. If it's going to be won, they've prepped really well for it, they haven't left much to chance."

Coming into this All-Ireland final, Kerry boss Peter Keane intimated that his side are somewhat in transition and are facing a more experienced outfit from the capital.

But McStay has dismissed that sentiment and insists that the Kingdom will be coming to Croke Park with the sole intention of upsetting Dublin's charge at history.

"In many ways, they're defending the great tradition of their county, and look who they're defending it against, their greatest rivals. 

"Peter Keane would love to peddle the idea that Dublin are a team for the ages and he can try it, but I don't think anybody's really buying it."

While McStay believes that Dublin will ultimately prevail, he's confident this will be a competitive final that will only be decided in the closing stages of the game.

"I think it's complete nonsense for people to think Dublin are going to go into double-digits. This would be the one final where they would love to maul Kerry once and for all. I have no sense that that's going to happen.

"I have it in my head three or four points [of a difference]. I don't rule out huge pressure points for Dublin because of the quality of the Kerry attack. You look at what Mayo did in the first half and weren't able to pad out the scoreline.

"I guarantee Kerry will be able to pad out the scoreline. If they get the chances in front of goal, they'll put them over the bar or in the back of the net. I absolutely don't rule out a contest. This is going to go down to the last 10 or 15 minutes but I can't argue against Dublin winning the All-Ireland."
