Brotherly love will be cast to one side on Saturday as MK Dons goalkeeper David Martin takes on brother Joe at Gillingham.
Like the sibling rivalry between George and Sam Baldock earlier this season, Martin has never come up against his brother in professional football.
But while he admits his parents will be in an awkward position at Priestfield come 3pm on Saturday, Martin wants to get one over his little brother.
“There are so many of us going, the family might have to take a stand out in Gillingham I think!
“It has made it even more interesting after Joe scored a free kick at the weekend, and he’ll be one to watch.
“I’m pleased Gillingham got their first win, but I hope we batter them 3-0!
“It was a great season for him last year, he got in the League 2 team of the year and he was Player’s Player of the Year.
“He’s the total opposite to me though, it’s like trying to get blood from a stone. Once I start talking, you can’t shut me up!
“We are all being professional about it, but it’s great to be playing against my brother.
“We did have the days when we were little, kicking him around the garden but I don’t think it’ll be like that on Saturday!
“I’ve never been in the situation before, but hopefully you just approach it like any other. He’s just another opponent.
“Unfortunately, goalkeepers can make mistakes but don’t you want to make them in games like this.”
But Martin’s copybook this season has been fairly blot-free so far.
Dons have shipped nine goals in the opening two months of the League 1 season, but Martin has barely put a foot wrong between the sticks.
And with Ian McLoughlin breathing down his neck in a bid to get in the first team again, the current number one is pleased with his form.
“I’m pleased with how it’s gone. I’m a perfectionist and every time I touch the ball, I think ‘what could I have done better?’ and there’s not one player who won’t make a mistake.
“Ian did really well last season, and all the lads were comfortable with him. And that was huge for him.
“It was frustrating for me to watch on from the sidelines, but that comes with the territory - there’s only one goalkeeper.
“This year, Ian has come back and looked at things differently, like he wants to be the number one.
“All I can do is keep doing what I am doing, stay professional, look after myself and treat every game like it’s my last.
“There has been a different dynamic in the goalkeeping union, but it has benefitted both of us.”
But it’s not just amongst the keepers that the dynamic has changed, according to Martin.
He feels Gary Waddock’s arrival as Karl Robinson’s second-in-command has brought with it a positive change in the way the team plays.
And those chances, Martin believes, should lead Dons to at least a play-off spot this season.
“This year, the gaffer has changed a lot of things. Gary Waddock coming in has been a huge catalyst in that.
“They’re putting their ideas together and we’re playing differently this season.
“We’re going for teams - that’s the only way to get promoted from this division.
“You can be defensively sound, but you’ve got to score goals.
“Potentially, we can knock on the door for automatic promotion, and if not, certainly the play-offs.”
