US Servannaise's domination continued for the next four years as they won five titles on the run, with each time the Stade Rennais UC second, less than five points behind the champions.

The President of the Stade Rennais, Isidore Odorico, brought several foreign players to the club (Lothka, Szabo, Nico...), but the side remained unable to win the Western Division, and President Odorico's attitude towards both amateurism and restrictions on foreign players conflicted with the Western Division's direction.

Rennais bought stars at a high price such as South-American Lucas Severino (140 millions of French franc),[7] Mario Hector Turdo for the Division 1 2000-01 but these players were all failures.

An agreement to transfer Moussa Sow to Lille OSC was completed in June and the arrival of Georges Mandjeck, Onyekachi Apam, Victor Hugo Montano and Johann Carrasso was confirmed the same month.
