Founded in 2023, Football Club MAS 31 emerged from the merger of three clubs: AS Mondonvilloise (1958), Etoile Aussonnaise Football (1966), and AS Seilh Football (1955). It is an association governed by the French law of 1901 and affiliated with the French Football Federation under the number 564480. Although each of our histories has been rich and exciting, this merger was seen as a natural step due to the geographical proximity of our three municipalities and the complementary nature of the three founding clubs. FC MAS 31 is not merely a football club; it is a family that draws its strength from the unity of three villages. Discover how we were "born" from the shared vision of Mondonville, Aussonne, and Seilh to create something special. At the heart of FC MAS 31, we celebrate values deeply rooted in respect, collaboration, and the joy of the game. Our commitment extends beyond the pitch and encompasses building lasting connections with our supporters and our communities.
