Mainz is also interested in William Bøving, a Danish forward born in 2003, valued between 8 and 10 million euros by Sturm Graz. Bologna and Nice are also interested in Bøving.

William Böving was initially reported by 'L’Équipe' to be close to transferring to FSV Mainz 05 for a fee of 4.5 million euros. However, Mainz's coach Bo Henriksen later stated that Böving is not an option for the club as every position is already filled, indicating that the transfer will not happen.

William Böving has emerged as a potential target for FSV Mainz 05, but a transfer would depend on further departures from the team. Böving's contract with Sturm Graz extends until 2026. The Danish forward, who has spent three years playing in Austria, made a strong impression last season by scoring eleven goals and providing eight assists in the league. Although Mainz 05 is contemplating him as a possible recruit, the chances of a transfer hinge on the exit of current players, a scenario that appears unlikely at present. Furthermore, SC Freiburg and Borussia Mönchengladbach are also considering Böving as a potential addition to their squads.
