Altach's 26-year-old winger Yann Massombo, who has both French and DR Congo nationality, is being linked with a move to Sturm Graz, as the football vice-champions anticipate further transfer activity following Ryan Fosso's departure. Sturm's sporting director, Michael Parensen, was reportedly asked about the potential transfer. Massombo joined Altach in July 2025 and his contract is valid until June 2027. Transfermarkt estimates his current market value at €800k.
