Kerry defender Jason Foley knows the Kingdom will need to tighten up defensively if they are to overcome Mayo this weekend.
The Kingdom won by three points against Munster rivals Cork back in June.
But the three goals conceded that afternoon will have raised fears in some quarters that last year’s defensive frailties haven’t been adequately addressed.
Mayo come into this game full of confidence, having seen off the challenge of Galway last weekend in a thriller.
Two early James Carr goals set them on their way in Limerick. And Foley hopes that lessons have been learned by his side from the Cork match.
“No team likes to be conceding three goals in any game so Donie [Buckley], Tommy [Griffin] and Peter [Keane] have been working really hard with us in training to put those things right,” he told the The Kerryman.
"We were very well defensively set up in the earlier part of the year but things happen in games.
“Sometimes you're going to concede goals in games. The opposition we've faced in Munster this year - Cork and Clare - have brought serious, serious stuff. And you can see they're on the brink of making some breaks as well. You have to give those teams credit. We'll work on it and hopefully put things right."
The big games will come thick and fast for the Kingdom now. After Sunday’s game in Killarney, they will face in-form Donegal at Croke Park. It would be a daunting prospect for players far older than Foley’s 22 years. But the Ballydonoghue clubman is embracing the challenge.
"I've lost in Croke Park a couple of times; I've won in Croke Park a couple of times," he said.
"It's obviously going to be very tough in a neutral venue. That's what you strive for, playing in Croke Park. And if you win there, even better.
"The new system is very positive for us. There are more games and as players, you want to be playing more games. You want to be tested against the best opposition possible.”
