The 25-year-old had a difficult season for Hellas Verona, contributing just one assist in 34 Serie A appearances — only nine from the start — and is not expected to remain at the club despite holding a contract until June 2029.
Brest, who finished twelfth in Ligue 1 this season, have emerged as a potential destination for permanent or loan acquisition.
Malmö FF had already sounded out Sarr about a potential return to his former club — possibly on loan — according to Gasetten, with the Allsvenskan side keen to strengthen their attack.
Sarr left Malmö for Heerenveen in January 2022 before moving to Olympique Lyon, then VfL Wolfsburg on loan, before Verona signed him permanently last summer.
The coming weeks will determine whether Sarr chooses the French route with Brest, a sentimental return to Sweden, or a third option that emerges from the market before the window closes.
