In the first Champions League round of 16 match against Leverkusen club, they will have to compete without midfielder Michael Ballack, who suffered a leg injury. The German got injured during training, so he will have to watch the match from the sidelines. The same goes for Sidney Sam and Eren Derdiyok. However, doctors are currently unable to predict when Ballack will be able to return to the field. This season, the 35-year-old veteran scored two goals in 14 matches in the German championship.
