Liverpool had taken a 12th-minute lead at Anfield through Cornelia Kapocs and were well on top.
But Vignola’s moment of magic in the 24th minute dragged her side back into the game.
She raced past midfielder Ceri Holland, carrying the ball from the halfway line towards Liverpool’s area, and fired it past goalkeeper Faye Kirby from a tight angle.
It was the spark Everton needed and Katja Snoeijs’ header on the stroke of half-time meant they went in at the break 2-1 up despite being heavily outplayed.
Toffees boss Brian Sorensen admitted: “In football there are things that happen that can change things in a game at the flip of a coin. She brought us back from a very deep place.
“I knew that we would come back then. I think that moment changed the game.”
And how Everton came back. Sorensen switched things up at half-time, introducing club record signing Ruby Mace in midfield and added experience in defence.
Vignola, who made two appearances for Barcelona at the start of her career, was braced for her opportunity nine minutes after the restart.
She got two in as many minutes and scored both. Suddenly, Everton were 4-1 ahead and well on course to extending their unbeaten run in this fixture to eight games.
Did Sorensen expect Vignola to have such an impact?
“No! Not three goals from her,” he added. “I expected her to score which is why I started her. She was superb and she has been like that in training.
“Her runs are so well-timed and the way she faces up and goes at players, she is excellent. She just wants to score.
“I said to her afterwards she has set the benchmark for what I want to see. She is still a young player though, so let’s see. Today was a good debut.”
