Following their successful debut against Olympique Lyonnais, the Red and Blacks, who were defeated this morning by Real Sociedad (1-0), had no choice but to win against En Avant de Guingamp in order to finish first in Group B and advance to the final.
Mission accomplished, as Sébastien Tambouret's men won 2-0 against their Costa Rican neighbours thanks to goals from Kelvin Dongopandji and Steeve Mvodo Mvodo.
Rennes will face AS St-Etienne tomorrow, Sunday, at 3:30 p.m.
