FSV Mainz 05 and 1. FC Köln are interested in Austrian defender Stefan Posch. The 28-year-old is currently a backup player at Como 1907. According to Fabrizio Romano, initial talks have begun for a potential winter transfer. Any deal is complicated by the fact that Posch is on loan at Como from FC Genoa, and that arrangement would need to be terminated first. He has 49 caps and 4 goals for Austria. In the current Serie A season, he has made 13 appearances and scored one goal. His current market value is €5.50m, according to Transfermarkt.
