26-year-old Frenchman will be playing for the club next season, club representatives announce.
The French team has been negotiating for a long time about the possibility of loaning this defender, and now everything is settled, as the new English club coach Rafael Benitez does not see Bruno in his starting lineup.
Cheyrou joined "Liverpool" two years ago from a French club, but he did not fit in England and spent a long time on the bench.
Meanwhile, "Marseille" coach Jose Anigo is very pleased with the new team member and hopes that Cheyrou will become an important player for the team.
"He is a very good player and our team needed such a footballer," Anigo said. "Bruno has a strong left foot, is athletic, and an excellent fighter."
"I think "Marseille" is exactly the place where he should recover after several unsuccessful seasons in England."
