On the field, the pair have helped Chelsea to the top of the Women’s Super League.
And after both played in Sunday’s 5-0 win at Bristol City, they opened their Twitter direct messages and encouraged people struggling with their sexuality to get in touch.
Harder wrote: “I’m lucky to have a family who was nothing but happy for me when I came out 7 years ago.
“I know a lot of people are struggling to tell their friends and families they are gay, which must be the worst feeling I can imagine.
“To come out should feel natural to anybody and likewise be accepted by everyone. For the next hours, MagdaEricsson and I will open our dm’s for anyone who struggles to come out, want to know about our experiences or just look for a good advice on Valentine’s day”.
Sweden international Eriksson added: “I’m so lucky to have a relationship with the woman I love but I know this isn’t the case for everyone, especially in these times.
“In the LGBT community these problems can feel even worse. So, for the next hours, Pernille Harder & I will open our DMs for anyone who wants to chat.”
