Kamaldeen Sulemana, Ghana’s attacker, left Stade Rennais for Atalanta Bergamasque after a two-and-a-half year stay in France. This transfer marks the fourth club for the 23-year-old in five years, after his arrival from Nordsjælland in 2021. During his visit to Rennes, Sulemana played 47 games, scored 6 goals and delivered 4 assists, although the club had a relegation to the Championship. The Atalanta Bergamasque has committed with the player for an estimated amount of 17 million euros, bonuses and resale percentage included.

At the same time, Stade Rennais is active in the summer transfer market. Ligue 1 changed its dates, with a mercato opening from 1 to 10 June and a reopening from 16 June to 1 September. Loum Chaouna, an attacker trained in Rennes, made a five-year commitment with Burnley, England, for compensation estimated at 15 million euros. He could be joined by his former teammate Andy Diouf, midfielder of Lens, also courted by Burnley for the same amount.

The Ligue 1 calendar for the 2025-26 season was also unveiled, with an important meeting from the first day against the Olympique de Marseille. The season will include derbys against Nantes and Brest, as well as a trip to the Parc des Princes against the reigning French champion Paris Saint-Germain. Albert Gronbaek, loaned to Southampton, joins the Genoa in Serie A for a new loan with option of purchase. Finally, Adrien Truffert, an iconic defender of Stade Rennais, left the club after ten years of service to join Bournemouth in the Premier League for five years.
