In their early meetings during the 1970s there was little indication the two would become deadly adversaries. The newly formed Parisians were trying to assemble a competitive team, while the Olympians were Ligue 1 contenders. It all changed in 1986, when PSG won its first championship and l'OM were bought by Bernard Tapie. By the end of the decade, PSG were fighting for the 1988–89 title against Tapie's star-studded Marseille, and sparks flew for the first time. The accusations made by PSG president Francis Borelli against Tapie and l'OM for fixing matches during that season were a big contributor to their growing antagonism.
