As part of a new documentary, Fletcher was joined by Ladies supporter Marcus Keam, who was offered a once-in-a-lifetime opportunity to train with the team.
After participating in the session, Marcus was introduced to the players before taking part in a penalty shootout against Reds goalkeeper Danielle Gibbons.
Fletcher said: “It was a real privilege to be able to visit the stadium to watch the girls train as they prepared for the new WSL season.
“This was a brilliant day for Marcus, who was able to meet some of his heroes and take part in the training session.
“I would like to thank Liverpool Ladies FC and Scott [Rogers] for allowing Marcus to live a lifelong dream and take part in the session.”
