On 15 March 2009, Marseille ended PSG's seven-game unbeaten streak and cost them the top spot. And that wasn't the worst of it.
PSG had won six of their previous seven matches to climb from sixth to second in the table. A victory over Marseille would have sent them into first over Lyon. But despite having won 2-4 at Marseille back in October, the rematch proved to be more difficult.
Playing before a crowd of almost 45,000 at the Parc des Princes, the visitors had a couple of close chances in the first five minutes and finally went ahead in the 24th minute with a goal from their Dutch midfielder Bolo Zenden (pictured). PSG's Ludovic Giuly equalized two minutes before the break, but the second half belonged to Marseille.
Shortly after the restart, PSG went down to ten men after Zoumana Camara was ejected for a challenge on Zenden, then Marseille extended their lead with goals from Bakari Kone (55') and Lorik Cana (61') to claim the 1-3 win. The real excitement came after the match, however, as clashes between the two supporters groups resulted in 22 arrests. It was the latest in a series of incidents in the rivalry dating back to April 1995, when 146 were arrested after a Coupe de France semifinal.
The loss dropped PSG back into sixth and sent Marseille up to second, which is where the teams finished the season.
