Dublin manager Jim Gavin insists his All-Ireland final squad is still open, as preparations begin for next month's clash with Kerry.

The five-in-a-row chasing Blues overcame Mayo on Saturday evening, but the 26-man team list didn't include seasoned players like Bernard Brogan, Eoghan O'Gara, or Rory O'Carroll.

The omission of the Kilmacud Crokes full-back was perhaps the most surprising one, after he had started the final Super 8s game against Tyrone in Omagh just six days previously.

Brogan and O'Gara both saw game time off the bench at Healy Park, with the latter scoring a late goal as the Dubs won by six points.

But Gavin, who played his final game in Blue in 2002, says that plenty can happen between now and 1 September.

"All they can do is try their best, and those guys are putting a serious amount of effort in," Gavin told RTÉ Sport.

"They are exceptional leaders, and have been for a number of years.

"All players will be disappointed when they don't get on a match-day squad. But make no mistake about it, they're pushing hard for a place on the pitch.

"In the shadows, they're influencing how this team performs.

"For the next day, there are still a lot of weeks to run, and a lot can change over that time, and we'll still be searching for the players who can perform consistently."

The Dubs trailed Mayo at the weekend, before blowing them away in 12 second-half minutes as Con O'Callaghan (above) scored two goals to turn the game around.

It might have been the best period of play that a Dublin side have put in since Gavin took over as senior manager for the 2013 season.

Was it the perfect display?

"Perfection is a bit like infinity," according to the 1995 All-Ireland winner.

"There's always something in each facet of play that you want to improve upon.

"We went through a patch in the game where we executed really well, but over the course of the game it will ebb and flow.

"When the opportunities come your way, you just need to execute them the best you can."
