With so much at stake, the club’s psychologist has been busy preparing them to play in front of a sold-out Wembley crowd.
“It’s really important. It allows us to train our minds,” said striker Martha Thomas.
“In the same way we train to get stronger with our muscles, we’re just getting stronger in our minds.”
One technique used by the players has been yoga.
Vilahamn says it has been key in their ability to score late goals this season, like they did in their 3-2 win over Sheffield United and 2-1 win over Leicester City.
“You can see the strength in the character of the players but it’s also part of the environment we are trying to create.
“One of the four key words in our environment is to be ‘present’. It’s about handling setbacks. It’s why we do yoga, so we can handle these moments.”
While not all players enjoy yoga, Vilahamn says it has made him a better coach and “a good leader”.
“I’m the first one to participate and I’m loving it the most,” he added.
“When I was introduced to it a few years ago it helped me to stay calm. I was very aggressive before and did substitutions when I got feelings.
“I think you should never take too many decisions on feelings, you should do it by being calm and using your brain. It helped me a lot to make the right choices.”
