Dunkerque, the northern club, is preparing to face PSG in the French Cup semi-finals on Tuesday at 21:10. Luis Castro, the 44-year-old coach, has transformed the club into an attacking team that likes to play with the ball. He arrived at Dunkerque in September 2023 to replace Mathieu Chabert and brought a new method of work made up of almost exclusively ball-based training sessions. Bruno Genesio, the coach of Losc, saw in Luis Castro's Dunkerque « a team that plays very, very good football, with good ball recovery principles, very interesting positions and a very precise game idea ». Luis Castro was never a professional player, but he studied football at the University of Bragance and was inspired by José Mourinho's FC Porto in 2002-2003. He also trained PSG players Gonçalo Ramos and João Neves during his time at Benfica Lisbon. The match against PSG will be a major challenge for Dunkerque, which must try to bother the unbeaten team in national competitions this season. And Dunkerque has already managed to eliminate two other Ligue 1 clubs away from home in the French Cup: Auxerre and Brest. So the northern club has the means to create a surprise. Luis Castro has confidence in his team and thinks that « it's almost mission impossible, but everyone thought it was mission impossible against Lille ».
