On 8 January 1978, Paris Saint-Germain turned the tide in their budding rivalry with Marseille. And they did it by a record margin.
While the contest, known as Le Classique or the Derby de France, has become one of the country's most heated rivalries, it started as a very one-sided affair. First played in 1971, Marseille won the first three in a row and seven of the first eleven while losing only once (a 2-0 loss in the Coupe de France in March 1975). By the time Marseille arrived at the Parc des Princes in January for the twelfth match of the series, they had taken three of the last four.
Playing in front of a crowd of 33,386, the visitors looked to continue their run of success, going ahead with a 12th-minute penalty from striker Sarr Boubacar. But PSG rallied to take a 2-1 lead into the break with goals from François Brisson (29') and Mustapha Dahleb (44').
In the second half, an own-goal from Marseille defender Marius Trésor (46') extended PSG's lead to 3-1, then a brace from striker François M'Pelé (pictured) (49', 82') took it to 5-1. The four-goal margin was the largest win of the derby and remains the record, though it was later matched by Marseille's 4-0 win in November 1986 and PSG's 1-5 win in February 2017.
Since then, the rivalry has been relatively balanced across all competitions, with a total of 38 PSG wins to 32 for Marseille.
