Joaquin Seys's entourage hopes for a significant transfer and considers a departure the logical next step, a detail that was added at the end of July. Seys has not made a public request to leave and has not expressed a wish to depart. According to DAZN, in September 2025 Seys said that he felt good and was happy where he was, and that it was a matter of mutual trust. He added that they would see what would happen that winter or the next year, stating that every year he listens, looks at the options, and then decides.

It is reported that SL Benfica are following Joaquin Seys. The English tabloid The Sun referred to a potential transfer fee of around 35 million euro. It is also reported that Club Brugge, where Seys is under contract until mid-2029, in principle does not allow him to leave this summer. Het Nieuwsblad reports that Club Brugge previously rejected a 35 million euro bid for Nicolo Tresoldi and is financially strong enough to keep Seys for at least one more year.

It is reported by Sudpresse that Benfica has been following Joaquin Seys for a period of time and would be prepared to submit an offer for him of around twenty million euro.

SL Benfica's interest in Club Brugge's 21-year-old Belgian left-back Joaquin Seys has been confirmed, and FC Porto is also an interested party. Links to Aston Villa have also been verified; the club is reportedly seeking a replacement for Lucas Digne. According to Het Nieuwsblad, Seys is not required to leave his current club but is considered a player who could be sold in a significant transfer, with the Premier League mentioned as a potential destination. It is reported that Club Brugge is aiming for a transfer fee between €30 million and €35 million for their youth product. Seys has six caps for Belgium, is under contract until June 2029, and has a current Transfermarkt market value of €20.00m. In the 2025/2026 Jupiler Pro League season, he made 54 appearances, scoring 3 goals and providing 3 assists.
