But the 38-year-old, who played at the Merseyside club for three years, has revealed he is desperate to score four goals to hit a century.
"You know how it is with goalscorers," he told So Foot.
"We love goals, we love hitting milestones; 25, 50, 75… for me, it's the landmark of 100 that haunts me, I've been stuck on 96 since I stopped.
"I am missing four goals and it gets to me, it drives me crazy! I want to come back to Ligue 1 to get them. If a club takes me, I can get them in two or three months.
"I'm ready to come back and play for free, without pay, so there isn't much of a risk for them. For the moment, I'm not in advanced talks with anybody but I hope that clubs will appear."
