Born on the French island of Reunion, Gauvin relocated to the south-west mainland of France at the age of four and joined Toulouse at the age of 12.
Gauvin has also shone for the French senior women's national team since 2015, when she earned her first call-up.
Early years at Toulouse
At the age of 16, Gauvin rose to Toulouse's senior team, who she represented in the Division 2 Feminine. In the 2012/13 season, Toulouse played in the top flight, the Division 1 Feminine, and Gauvin got her first taste of top level French football. However, they were relegated and immediately dropped back down.
Move to Montpellier
According to Everton's official website, Kirk said: "Signing Valerie is a real coup for the club and a sign of our ambition.
"Sarvar (Ismailov, Everton Women Sporting Director) has worked tirelessly to get this deal done, and it shows his commitment and ambition to the club with what we want to achieve here."
The presence of France teammate Maeva Clemaron helped Gauvin settle at Everton and she scored four goals in the first seven matches of the 2020/21 season.

"It's nice to have Maeva playing behind me," Gauvin said, according to The Guardian. "It's helped me a lot in terms of understanding the language and in particular the instructions of the coach because it's a different playing system to what I've been used to.
"The role of Maeva has been vital both before I came and after. Before I arrived I spoke to her on the phone and she gave me some advice about what it was like from an insider's point of view."
