Mainz have signed permanently on-loan Getafe midfielder Eugen Polanski.
The 24-year-old was loaned from the Spanish club until next June, but he has now agreed on a new three-year contract with the Bundesliga side and will not be returning to Spain next summer.
"Mainz is an excellent club for me," reported the midfielder. "Next year, we will move to a fantastic brand new stadium and I feel very happy in the region with my family.
"I am really glad to have completed this transfer so soon as this gives me room to plan beyond next summer."
