This weekend's clash between Dublin and Mayo is a hugely intriguing one for the neutral GAA fan.
Those two counties have shared some epic battles over the last decade or so, although it is difficult to take much away from those games considering how different both teams are in comparison to those fixtures.
There are plenty of question marks surrounding both sides heading into the game. Dublin are largely untested up to this point, cruising through Leinster and facing only one Division 1 team in their All-Ireland round robin. As for Mayo, they have mixed some scintillating football with spells of incredibly poor play, meaning it is difficult to know what sort of form they will be in on Sunday afternoon.
Lee Keegan holds Mayo concern ahead of Dublin clash
As well as rightly praising them on occasion, Lee Keegan has also questioned Mayo at times this year, believing his old team have often lacked the consistency needed in order to compete for the Sam Maguire.
Writing in his column for RTÉ, he identified one particular area that he holds concerns over heading into the game against Dublin.
Kevin McStay will have concerns, notably around kickouts.
If Dublin review that first half in Pearse Stadium, you wonder will they be inclined to put a huge press on. The Salthill wind was a big factor but either way, if Dublin push up, it'll really test Colm Reape.
He's a superb keeper, player of the match in the league final, but his deliveries will have to be pinpoint the next day. It'll be a real test of the variety of kicks, can he go long, can he go short?
Lee Keegan is spot on here.
Galway put serious pressure on the Mayo kickout during the first half in Salthill, with McStay's side winning only four of their 13 restarts in the opening 35 minutes.
In saying that, Galway only managed to generate three scores from those turnovers. It was something Peter Canavan said could come back to bite Padraic Joyce's men and that indeed turned out to be the case. If Dublin can apply a similar sort of pressure, you would imagine that they would be more efficient in making the most of their opportunities.
Kick-outs often prove to be a decisive factor in big championship games, meaning both teams will be keen to get them right on Sunday.
Mayo have been at their best when playing under the cosh in recent months, something that could well work in their favour in this fixture. As for Dublin, they have been steadily building this season in hopes of peaking for this stage of the competition.
Time will tell which team's approach will win out on this occasion.
