In the domestic league, Astra managed to impress. Despite having a poor start which included a severe 1–5 defeat from vice-champions ASA Targu Mures, the "Astralii" managed to finish the regular seasons champions. During this time, however, manager Marius Șumudică was convicted of betting on domestic matches, prompting his suspension by Romanian FA for the remainder of the season. On appeal, Șumudică managed to reduce his suspension to two months, and also begin to apply at the start of the 2016–17 Liga I. On 1 May 2016, after a draw between FC Steaua and Pandurii Tg. Jiu, Astra Giurgiu won the 2015–16 Liga I. This was Șumudică's first domestic title, and also made Giurgiu the 13th Romanian city to have won a national title, after Bucharest, Timișoara, Ploiești, Arad, Craiova, Cluj-Napoca, Pitești, Oradea, Brașov, Reșița, Urziceni and Galați. Astra also later won the 2016 Supercup against CFR Cluj.
