 In 1993, Rousset was surprisingly transferred to Olympique de Marseille, who were the reigning European Champions but embroiled in a corruption scandal.The presence of rising star Fabien Barthez ensured Rousset did not start a competitive match for the club and when Marseille were forcibly relegated in the summer of 1994, as punishment for their match fixing crimes, Rousset (and many other established players) were sold.Rousset spent the next season with Stade Rennais before moving to Scotland to join Heart of Midlothian in 1995.
