Anderlecht has reportedly reached a personal agreement with Siebe Van der Heyden, a former Union player, as part of their strategy to strengthen their defense in light of injuries to players like Jan Vertonghen.

Siebe Van der Heyden is being considered by Anderlecht as a potential defensive reinforcement. He has a history in Belgium with Union SG and has been part of the Belgium national team. A personal agreement with Anderlecht seems to be reached.

Olivier Renard has shown interest in Siebe Van der Heyden, who has fallen out of favor at Mallorca after his transfer from Union. Multiple sources confirm that he is a priority for Anderlecht. Van der Heyden is open to returning to Brussels, where he previously became a cult figure. Anderlecht is considering a loan with an option to buy, which is seen as the only viable option for an agreement. Van der Heyden is seeking more playing time as he is currently benched at Mallorca.

Siebe Van der Heyden, who transferred to Mallorca from Union for nearly three million euros one and a half years ago, is reportedly being targeted by Anderlecht. Although he has been largely out of the picture this season, Van der Heyden is content in Mallorca, where he remains under contract until mid-2028. Nevertheless, he has indicated a willingness to return to Anderlecht, a club where he spent a significant portion of his youth training. According to transfer expert Sacha Tavolieri, Anderlecht is seriously considering him to fill the left centre back role. The club is expressing concrete interest in Van der Heyden, a native of Brussels, although his current club may wish to recover some of the transfer fee they initially paid.
