Marlon Mustapha has agreed to a one-and-a-half-year loan deal with Altach that will last until the summer of 2026, including an option to buy. His return to Austria came as a surprise due to past complications with military service obligations. However, he was able to join Altach after resolving these issues with the Austrian military. The transfer was made possible through discussions between Altach's team management and the Austrian military, with the Austrian Football Association (ÖFB) playing a mediating role. Mustapha has successfully completed a medical examination and has commenced training sessions.

Kicker has reported on Marlon Mustapha's return to Austria and his signing with SCR Altach. Marlon Mustapha is returning to Austria after two and a half years and is set to play for SCR Altach until the summer of 2026. He has entered into a loan contract for one and a half years with SCR Altach, which includes a purchase option. The relatively long duration of the loan deal is attributed to Mustapha's obligatory military service in Austria. It has been noted that the club, the player, and the Austrian armed forces are in discussions to find a solution regarding his service.

Marlon Mustapha, a forward born in 2001, has been loaned from Como to SC Rheindorf Altach, a club in the Austrian Bundesliga, until the end of the season. He was previously on loan at Greuther Furth in Germany earlier in the season. The transfer is a temporary move, as officially communicated by Como 1907.

Kicker provides an update on Marlon Mustapha's early departure from Fürth. Marlon Mustapha is leaving Fürth earlier than planned. The club, together with Como 1907 and the 23-year-old Austrian striker, has agreed to terminate the loan, which was originally set for a year, prematurely. 'The loan certainly didn't go as all parties involved had imagined,' explained sporting director Stephan Fürstner. Mustapha, who played in ten second division matches, can now 'reorient himself'.
