IT'S become quite commonplace to see a Brennan lifting championship silverware over the past decade and now the youngest of the brothers is chasing another major trophy - but not with Mattock Rangers.
The Brennans have been synonomous with football in Collon, but intercounty star Mark made the switch to St Sylvester's in Dublin a couple of seasons back and now Keith is plying his trade with neighbouring Hunterstown Rovers after being granted a transfer.
'It's not really been like a new club because I've known the lads for years, it's been very easy to settle in and even the style of football is the style I like to play,' reflected Keith as he looked forward to Sunday's showdown.
'I was getting plenty of football with Mattock alright, won two championships and had plenty of great years, but I had my heart set on moving.
'I don't want to say too much about it, but Hunterstown is a very important club for myself and my family and it was a team I wanted to join. The time was right this year and hopefully I'll be proved right.'
Needless to say, centre-back Keith (24) can call on the advice of his siblings at any time and that's been a great source of encouragement both to him and players outside the family.
'I will always get advice off them whether it by text messages or words. I've been learning off them for years and it was something I was able to bring to Hunterstown and share with them.
'I've had more from David being the defender; he made my job in Collon much easier when I moved into the backs.
'But Mark would always have advice too and being one of the best footballers the county has ever seen you would always take note of what he had to say.'
It's been a case of 'so far so good' for Keith and his Hunterstown colleagues who have a 100% record from their four championship outings to date and in terms of the scoring they haven't looked to be in danger in any of their games.
'It's been brilliant so far,' Keith acknowledged. 'It's great to see a reward for all the hard work we are doing and to see it out would be even better.
'The group we had was tough, but from the start we played well and it's been great to get the scores we did. Westerns were tough enough [in the quarter-final]. They put it up to us, and it's tough no matter who you play when it comes to the championship.'
Hunterstown's semi-final experience doesn't necessarily support that last theory as they completely steamrolled Sean McDermott's, storming into a 4-7 to 0-3 half-time lead before going on to win by a massive 23 points.
Looking back, Brennan said: 'We put our plan in place and from the moment the ball was thrown up the plan worked.
'During the year we've been trying to work on killing teams off. There were games where we were 10 or 11 ahead and let teams back into it, so it was great to get such a good score.
'But lads will want to go a step further from last week when it comes to the final and everyone will be hungry for the ball. We certainly won't be getting carried away.'
It goes without saying that Hunterstown will be paying little heed to the 0-16 to 2-3 win they enjoyed over the Togher outfit earlier in the championship, and Brennan feels they will be a stronger proposition come next Sunday.
'I think we caught them on the hop the first day. The first time out in the championship you don't really know what to expect and going into the final we'll be respecting them because they're not in the final for nothing.
'Plunkett's were the favourites to go through to the final and Togher beat them, so you'd expect that the team who beat the favourites are the favourites in the final.
'But we'll be concentrating more on our own game. Everyone in the camp will be in good form, everyone knows the roles they have and it's a matter of putting them into place on the day.
'Finbarrs have the experience of winning this final, but it's more about who wants it more. Everyone's happy that we've made it to the decider and there's excitement around the area because it's 19 years since there was a big final around the place.
'Hopefully we can go all the way and Hunterstown will be hopping for a few days afterwards.'
