Bild has reported that 24-year-old Lasse Rieß has completed a loan move to Fortuna Düsseldorf from Mainz.

According to information from 'Bild', Mainz 05's German goalkeeper Lasse Rieß will be loaned for one year to Fortuna Düsseldorf, a club recently relegated to the third division, with no option to buy.

Before the loan is completed, Rieß's contract at Mainz, which expires in 2027, will be extended. Rieß made 6 appearances in the Bundesliga for Mainz during the 2025/2026 season. His current market value is €500k, according to Transfermarkt.
