Both Florian Plettenburg of Sky Sports Deutschland and Sportitalia transfer pundit Alfredo Pedullà are confident that a deal should be reached to make the move to Mainz permanent over the next 24 hours.
Intensive talks are taking place to get an agreement over the line, as Mainz are determined to lock Posch down.

What happened
Negotiations between Serie A side Como and Bundesliga club Mainz 05 for the sale of defender Stefan Posch have intensified. The Austrian international is understood to be keen on the move, and discussions around fee and personal terms are progressing. Posch has been a regular in Como's defense but the club appears open to cashing in on the player as Mainz look to strengthen their backline ahead of the new season.
Chance analysis
A potential Bundesliga-to-Serie A reverse move that would see Mainz 05 acquire an experienced Austrian international defender. For Mainz, Posch would add physicality and top-flight experience to their defense, addressing a clear squad need. For Como, the sale represents capital generation and squad reshaping under their ambitious ownership project. The intensifying talks suggest a deal is close, though Bundesliga and Serie A market dynamics may influence the final fee.
Como likely to lose a starting defender; Mainz 05 set to gain Bundesliga-ready center-back reinforcement if deal completes.
If confirmed, Posch's departure weakens Como's defensive options while strengthening Mainz's backline ahead of their Bundesliga campaign.
