Williams became the most-capped player in England history after featuring in the stunning 4-0 friendly win for Mark Sampson's side against Sweden last Sunday.
And Liverpool striker Longhurst praised the precociously-talented midfielder who she believes epitomises what women’s football is all about.
“She’s normally really talkative but she has been pretty quiet this week really,” Longhurst told Sky Sports.
“Fara’s been pretty down to earth and she hasn’t really said anything about it to be fair, but we know how proud she is deep down to have reached that milestone and she deserves it.
“She was one of the players that really inspired me growing up and just to play alongside her has been an honour, but for her to get 130 caps speaks volumes of how hard she’s worked and how good a player she is.
“She always analyses the game and she’s a real deep thinker. She knows what she’s talking about but in training sometimes you just can’t get near her.
“She’ll do something and then before you know it she’s hit a 40-yard pass across the pitch – she’s a big influence on the rest of the team and when she plays well everyone steps up.
“Fara’s a really big character to have in the dressing room and in some ways I think she really epitomises what a lot of people in women’s football have to go through.
“It’s not about the money, it’s about the passion and playing for the love of the game and she really has passion in abundance.”
Defending FA WSL champions Liverpool face a test of their title credentials this season when they host second-placed Chelsea at the Widnes Select Security Stadium on Sunday.
Lucy Bronze, Gemma Bonner, Natasha Dowie and Williams have all returned from international duty with England and Longhurst hopes the quartet will be buoyed after their victory against Sweden.
She added: “The girls (who represented England) got a good result against Sweden and they’ve all come back and brought a really positive energy back to Liverpool as well which is good.”
