OM were strongly fancied to go all the way and win the competition after beating Paris Saint-Germain in the previous round, but instead they went out against opponents who had never previously reached the quarter-finals. Jordan Veretout had Marseille in front at half-time after opening the scoring on his 30th birthday, but Annecy equalised early in the second half through young Ivorian striker Moise Sahi.
Defender Kevin Mouanga then headed Annecy in front, and the home side squandered a chance to equalise when Alexis Sanchez had a penalty saved, a spot-kick that had been awarded for handball following a VAR check. Yet Marseille, the 10-time French Cup winners, did equalise in the 96th minute.
With no extra time before the final, that meant penalties, but it was Annecy, sitting in mid-table in Ligue 2, who prevailed in decisive challenge when Marseille's Leonardo Balerdi put the crucial kick wide.
