The Olympique de Marseille has experienced a turbulent summer mercato, marked by complex negotiations and changes in situation. The case of Joel Ordóñez, a defender of Bruges, was particularly followed, but ultimately failed despite a first agreement of EUR 25 million. According to Romain Molina, Bruges manipulated OM hoping for a more lucrative offer from the Premier League, and the absence of this offer led OM to turn to West Ham player Nayef Aguerd as Plan B. This strategy, while risky, allowed OM to fill a defensive need. The negotiations also involved agents such as Mounir Sidhoum, whose role was emphasized by Molina.

On the sporting front, OM suffered a defeat against OL, marked by the expulsion of young defender Coenrad-Jadeen Egan-Riley. This suspension of one game, followed by another suspended, will see him miss the next match against Lorient on September 12. However, this absence is offset by the arrival of major reinforcements such as Benjamin Pavard and Nayef Aguedd, which reinforce the depth of the defensive force. OM will have to do without Egan-Riley for the match against Lorient, but will be able to count on a more complete team to face Paris Saint-Germain on September 21.

Ligue 1 officially scheduled the 7th day match against Metz on Saturday 4 October at 5 p.m., a schedule dictated by European constraints and television broadcast on BeIN Sports 1. This calendar is particularly dense for OM, with six matches in three weeks, including championships, European Cup matches against Ajax Amsterdam and Real Madrid, as well as shock against PSG. The international truce of September 2025 will see many players from Marseille integrate their national selections for the World Cup playoffs 2026 and other competitions.
