Wales will be competing in a play-off final for a second time, having lost 2-1 to Switzerland in a World Cup play-off final in 2022.
However, that was a one-legged tie with Wales having to play a semi-final in the lead-up to the match, and Fishlock feels the experience can be of benefit as Wales look to beat a side that played in that World Cup.
“When we played Switzerland, they didn’t have a semi-final and we flew there to play three days after playing 120 minutes,” Fishlock added.
“Switzerland hadn’t played and had a 10-day camp. They were floating on air compared to us.
“The emotion that the win takes us out of your body, the Bosnia game just drained us completely. This is two legs and we look forward to that.”
Fishlock will be 38 years old by the time Euro 2025 kicks off and says the thought of the end of her Wales career has popped into her mind.
“Everyone knows how much playing for Wales means to me and what it would mean to get to a major tournament. It’s not just about me. Everybody wants it. Everyone has their stories and their dreams,” she said.
“I have played for Wales for a very long time. There is going to come a point when I no longer can and that is just a reality. I am going to have to let it go at some point.
“That will probably be the hardest moment of my career. But it will also be an important moment in my life. How much I have achieved within that does give me some peace about it.
“I know deep down I am ready for that moment, but it will be tough for sure.”
