Round of 64
Following a Cano goal at the death in their last match of the Division 2 season, Rennes made their return to Division 1 three years after being relegated. In the close-season, the Red and Blacks lost the emblematic figure of Van den Boogaard, but made a good move in signing Omam-Biyik from Laval, just before he made an impression at the World Cup in Italy. Rico, Paillard and L’Helgoualc’h completed the list of new recruits. Under the stewardship of Kéruzoré, they got off to a good start to the season with 2 wins and 2 draws, the club suffered badly as of mid-August going on a winless run of 10 matches which lasted into November. The long-term absence of Denis was compensated for by the wildcard Oosterveer in the Autumn, and he brought some much needed solidity to the team as whole. Rennes then had a plethora of draws (5 in a row at the beginning of 1991) and were unable to swim in the calmer waters further up the table. Despite the excellent season of Omam-Biyik, who scored 14 goals, Rennes, who were crucified by off-the-field disagreements between President Ruello, and Manager Kéruzoré, finished bottom of the table, and were preparing for return to the Second Division when the administrative relegations of Brest, Nice and Bordeaux saved them. In the French Cup, it was inevitably Van de Boogaard who scored the goal for Rouen in the Round of 64 that knocked out Rennes.
