According to BILD, Beşiktaş was approached regarding Mustafa Hekimoğlu with a loan request including a purchase option worth €5.5 million. Ultimately, Schalke are said to have withdrawn.

According to ‘Sky’, Schalke made an attempt in recent days to sign striking talent Mustafa Hekimoglu from Besiktas. Schalke is said to have offered a loan with a €5 million purchase option, while Besiktas demanded €10 million. Schalke is currently no longer pursuing Hekimoglu.

Schalke 04 expressed interest in 19-year-old Turkish Centre-Forward Mustafa Hekimoglu, leading to a video call between the German club and Besiktas. During the discussions, Schalke proposed a loan deal that included a €5 million purchase option. Besiktas, however, demanded a higher amount, causing the negotiations to be paused. Hekimoglu's contract with Besiktas runs until June 2028, and his current Transfermarkt valuation is €5.00m. He has 7 caps and 1 goal for the Türkiye U21 team but did not make any appearances in the Süper Lig during the 2025/2026 season. Other clubs that have been linked with the player include Real Sociedad, Wisła Kraków, FC Utrecht, and Vitesse.
