If Great Britain manage to move past reigning champions Canada, then they will face Slovakia in the semi-finals.

It's been some week for Matej Liptak's side. First, they saw off 18-time champions United States and earlier today, they defeated seven-time champions Australia 2-0 to reach the last four for the first time since 2013.

Remember this?!

Leylah Fernandez, Canada's leading player at this year's BJK Cup Finals, was the person Emma Raducanu defeated in the final of the 2021 US Open.

Since reaching the New York showpiece over three years ago, Fernandez has cemented her place as a top-50 player and gone on to win two WTA titles.

Britain's Raducanu, meanwhile, has been hampered with injuries and has is yet to add any more silverware to her collection.

The pair won't meet again today as Katie Boulter has been giving the task of beating the Canadian number one.

They're currently tied 1-1 in their head-to-head record, with Fernandez defeating the British number one 6-4 6-1 in their last meeting in 2023.

Canada might not be particularly fearsome on paper but, as they showed last year, are greater than the sum of their parts.

Leylah Fernandez, who Raducanu famously beat in the 2021 US Open final, flourishes in this environment. The world number 31 is aiming for a seventh consecutive BJK Cup win when she faces Boulter.

Teenager Marina Stakusic earned crucial victories on her debut in the competition last year and is battling the resurgent Rebecca Marino for the spot in the opener against Raducanu.

Then there is Gabriela Dabrowski. The third-best doubles player on the WTA Tour has just won the season-ending finals and will forge a formidable partnership with Fernandez if required.

Getting the job done in the singles feels key for Britain.

And here comes Billie Jean King. The tennis legend, who this tournament is named after, presents Canada's Gabriela Dabrowski with a 'commitment trophy'. It's a very, very tiny silver cup.

Former British number one

Great Britain were so impressive, winning comfortably in both singles matches [against Germany] and I'm sure that sent a message to the other teams.

Defending champions Canada will be feeling the pressure so all to play for for Great Britain.

Emma Raducanu got Great Britain off to the brightest of starts on Friday, sailing past Germany's Jule Niemeier with a 6-4 6-4 win.

The 22-year-old was playing her first match in almost two months because of a foot injury, but produced an encouraging display in the 12-nation women's team event on her latest comeback.

"I think this event is a great way to come back, even though there is some pressure to score a point for your team. You're not just playing for yourself, you're playing for everyone," Raducanu said afterwards.

Then came Katie Boulter, with the British number one ensuring GB progressed without needing Olivia Nicholls and Heather Watson to play in a deciding doubles match.

Boulter, who is fresh from breaking into the world's top 25, needed 70 minutes to beat Laura Siegemund 6-1 6-2.

You could hear it being whispered in the breakfast hall of the Malaga hotel where travelling British fans were tucking into their Spanish tortillas.

"We could go on and win this, you know," one man cautiously confided to the table the morning after Great Britain reached the quarter-finals.

The nation has never won the Billie Jean King Cup.

But the feeling is growing that this year's event could be as good a chance as any.

"I said it before the competition started, I really believe that we can win this. I don't have a problem saying that out loud," said British captain Anne Keothavong
