A place in the Euro 2025 quarter-finals is at stake as defending champions England face tournament newcomers Wales.
This decisive Group D match will see England as the strong favorites when they meet Wales in St Gallen, Switzerland, at 20:00 BST on Sunday.
England, ranked 25 places above Wales in the world rankings, need a victory to secure their progression to the knockout stages.
Wales aim to cause an upset, but only a significant win would keep their quarter-final hopes alive.
'It's Now the Most Important Game'
Fans are flocking to St Gallen in anticipation of the showdown between the two home nations, with much discussion about their historic sporting rivalry.
However, England defender Alex Greenwood described it as just a "normal" game, not focusing on the rivalry.
"Personally, it's another game. It's now the most important game we want to play," Greenwood stated.
"That's my perspective, and that's how I treat it. For the fans and everyone involved, it's brilliant.
"The atmosphere will be fantastic and something we all look forward to. But from a personal standpoint, it's another crucial game."
The Lionesses had a rocky start in Switzerland with a 2-1 loss to France but rebounded with a 4-0 victory over the Netherlands on Wednesday.
This win revived their quarter-final aspirations and put their fate back in their own hands.
The Welsh camp suggested that the pressure is on England, but manager Sarina Wiegman appeared unfazed.
When asked if Wales were attempting mind games, she replied, "Maybe, I don't know. But we have our preparations and understand what's at stake.
"We will do everything to win because we want to advance. There's always pressure on England due to expectations.
"I've learned a bit about the history and rivalry. But again, we focus on our strategy and finding a way to win."
'Pressure All on England'
Wales captain Angharad James and manager Rhian Wilkinson believe the pressure is on England in St Gallen.
James expressed her team's desire to cause an upset and eliminate the reigning champions from Euro 2025.
Though a four-goal victory seems unlikely, Wales would cherish a first win against a top 10-ranked nation, particularly against their biggest footballing rivals.
"It's a rivalry match and one everyone wants to play in," she told BBC Sport Wales.
"The pressure is on England. They must perform. We believe we can challenge a top team. We are ready for the fight.
"As a Welsh woman, do you want to knock England out? Of course. It's in our blood and DNA. The rivalry has always existed."
Wilkinson compared the rivalry with England to her experience as a Canadian international against the United States but warned England not to underestimate Wales as her team has nothing to lose.
"It would be detrimental for them to overlook us, but that's their issue. I understand a grudge match with neighbors. I can't deny the history there," she said.
"England is a strong team. I'm eager to see our incredible women compete against them. The pressure is on them. We know there's still a chance. What do we fear? It's an exciting opportunity.
"With England, there's a storyline. Everyone is here for a reason. First for women's football, and secondly, why not embrace a rivalry?
"England will be compelled to field a strong lineup because the group is so competitive... so for my team, we have the chance to spoil the party, and that's a wonderful role."
Captain James has a personal connection to the opposition, being married to England international Amy James-Turner, but she insists her wife will support Wales.
"Amy will wear Wales' red shirt," she said. "When the groups were drawn, that was my first question - who will she support? She's Wales through and through."
