Olympique de Marseille coach Elie Baup has expressed his disappointment at his side's 4-1 hammering by Valenciennes on Sunday afternoon.
L'OM had previously won all six of their Ligue 1 encounters this season, conceding only once, but were soundly beaten by Daniel Sanchez's outfit.
Baup lamented the fact that 'nothing worked' for Marseille in a tough encounter, but insisted that the club must now look ahead to a much bigger test against rivals Paris Saint-Germain.
"There is both a lot and not a lot to say. For the first quarter of an hour our opponents suffocated us. We didn't manage to put anything together," Baup told reporters after the match.
"We really started the game badly all over the pitch. It's tough to concede four goals in a single game when before we had conceded once in six.
"We have to look forward without forgetting what has happened in our first seven games of the season. Nothing worked today. We didn't take things lightly though. Our opponents pressed us, and deprived us of the ball. We were also dominated in the air.
"It's tough when you're 3-0 down at half-time, that affected the team. We're going to talk things over, and work. We mustn't get too bogged down in a heavy defeat like this one.
"We have to quickly focus on what's coming, and get ourselves turned around."
