The Auxerre match was a very bad match for Marseille. While Marseille is aiming for the Champions League, they will not be able to recover from such a defeat psychologically. In the match in which they conceded 3 goals, they had statistically destroyed their opponent on the field. However, football is not a game of statistics. The one who scores the goal wins the match. And indeed, that is what happened and Marseille lost.
Have you read some of the rumors and news circulating regarding Marseille lost to Auxerre?
Pablo Longoria made surprising statement by saying that the referee in the Ligue 1 match was corrupt, haha this is an incident where someone who is angry and does not accept being lost, it can get Marseille into trouble.
I saw Marseille dominate completely but luck was with Auxerre because they could use every opportunity to score goal, although little disappointed but the result cannot be changed that Marseille lost badly.
