Mainz have completed the signing of Croatian international goalkeeper Dario Kresic.
Kresic has arrived from Lokomotiv Moscow on a free transfer in a deal until the end of the season.
Mainz general manager Christian Heidel says the deal includes an option for a two-year contract from July 2014.
29-year-old Kresic is a former VfB Stuttgart goalkeeper who has not been first choice at Moscow's Lokomotiv Stadion under manager Leonid Kuchuk this season.
"We have been in touch with Dario Kresic on some occasions in the past, now we had the opportunity to succeed with a move," said Heidel.
"We are delighted about that. (Dario) Kresic is an experienced shot-stopper, he will be in competition for a first XI role at our club from now on."
