The Dubs' biggest fan, Molly McNally (7), will be there to cheer on the Boys in Blue this Sunday after a successful campaign by supporters turned up tickets.
Molly's dad Gerry (47) said that she cannot wait to see Bernard Brogan and the lads in action against Kerry.
He said the Hill 16 Army supporters page on Facebook had put up a "Get Molly to the Final" post which was widely shared.
Dublin TD Mary Lou McDonald gave her own two tickets to the family.
"Mary Lou got in touch with Hill 16 Army.
"She got my number and donated her two tickets to Molly," said Gerry.
Meanwhile, it emerged yesterday that Molly had won an eircom Facebook competition for an adult and a child ticket.
The prize will also allow her to be a flag bearer on the pitch on Sunday, her proud dad said.
Gerry said that he was delighted that his family would now be able to attend the crucial match.
He said that the last two weeks of treatment were tough because Molly had a lot of injections, so this was something for her to look forward to.
"This morning she had her jersey out. She thought it was today," he said, laughing.
"We are counting down how many sleeps there are to the match," added Gerry.
Molly has another 12 weeks of immunotherapy left as part of her treatment for neuroblastoma.
The family were thrilled earlier this month that her latest scans were clear, meaning that the brave Dubs mascot is in remission.
However, her treatment continues, with more scans and assessments to follow.
Meanwhile, Mary Lou McDonald said that she was delighted that Molly would be attending the match.
"That's the best omen yet for the Dubs, that Molly will be there in the crowd cheering them on," she said. Ms McDonald got in touch after learning there was a shout-out for tickets for her.
"The most important person to be there is Molly. Her dad tells me she is in good form and she is certain we are going to win. I am taking my lead from her," said Ms McDonald.
"There is something very special about Molly. "She is a very brave girl. It would not be right, and it wouldn't be the same if she wasn't there," she added.
