Bayer 04 Leverkusen signed Croatia defender Vedran Corluka from Tottenham Hotspur on Tuesday on a loan deal until the end of the season.
Leverkusen also obtained an option to sign Corluka on a longer contract, without elaborating.
At the same time, Michael Ballack’s agent said the former Germany captain would not be leaving the club in this window.
Sports director Rudi Voeller said Corluka was exactly the kind of versatile defender Leverkusen had been looking for.
“He can play not only rightback, but also in central defense and on the left,” Voeller said.
Shortly before the transfer deadline expired on Tuesday, FSV Mainz 05 announced that Egypt striker Mohamed Zidan was returning to the club from Borussia Dortmund.
Zidan arrives on loan until the end of the season, but Mainz have the option then to sign him for two seasons.
In other Bundesliga last-day transfers, SC Freiburg said they were taking striker Ivan Santini from the Croatian club Zadar on loan until the end of the season.
Kaiserslautern added midfielder Ariel Borysiuk from Legia Warsaw, giving him a contract through June 2016.
Two strikers left VFL Wolfsburg on loan deals until the end of the season: South Korea international Koo Ja-cheol went to Augsburg and Srdjan Lakic of Croatia moved to TSG 1899 Hoffenheim.
