Defender Luca Caldirola underwent a successful operation on his left foot on Thursday. The 26-year-old was operated on by Prof. Hahn in Klinikum Mitte who removed a tile and a screw from Caldirola’s left ankle which had been in place since he sustained the injury last autumn. The Italian, who is currently out with a broken bone in the centre of his right foot, will carry out his rehabilitation in Bremen and work towards a comeback.
