Reece and Lauren James will trade childhood keep-ball battles for a crack at FA Cup history this weekend.
The Chelsea siblings can become the first brother and sister to win the men’s and women’s FA Cup titles.
Thomas Tuchel’s team will take on Liverpool in Saturday’s men’s FA Cup final, before Emma Hayes’ side will face Manchester City at Wembley in Sunday’s women’s showdown.
“When we were young, if I was trying to get the ball off Reece, he wouldn’t want to let me win the ball,” said Lauren James.
“And that would obviously get me frustrated. So it’s little situations like that, that stand out looking back.”
Successful coach Nigel James has underpinned Reece and Lauren’s rise to prominence, running his own academy and helping launch countless top-level careers.
“Every brother and sister or sibling would have that kind of competitive edge,” said Reece James.
“We always just want to do the best for each other and the best for ourselves.
“And that definitely drove us both to get to where we are today.
“Well it definitely didn’t make us worse, but that’s all I have to say about that!
“Our dad’s definitely had a big influence on where we are today, he’s definitely proud of us both representing Chelsea, growing up both supporting Chelsea.
“So to support them now is a great feeling as well. We’ve both put in a lot of hard work in our football to get to where we are now.
“We’re definitely very proud of what he has achieved in coaching, with his academy and helping a lot of young players.
“Providing opportunity is one thing, but taking opportunity is another. Having it in front of you is a hard thing, but taking it with both hands and not letting it pass is probably the harder thing.
“And it’s just trying not to miss the opportunity.
“There’s obviously a great piece of history there this weekend if we can both do it. But we can only take it one step at a time.
“We’re both really looking forward to the weekend, and our aim is to win both trophies.”
Chelsea’s women beat Manchester United over 4-2 at Kingsmeadow last weekend, to claim a third-straight league title.
Now boss Hayes’ side will look to add another FA Cup crown to their ever-increasing trophy haul, with Lauren James hoping for her first Wembley outing.
“It’s a big occasion at Wembley, but I just have to look at it like any other game, although it is a special moment,” she said.
“The aim is always to win trophies, and to do that you’ve got to stay focused.
“If you let things distract you it can kind of show on the pitch.
“We have a good group to not allow those distractions and keep focused.”
