Surgery in the USA
The centre-back has however re-ruptured the same ligament and will undergo surgery at Dr. Richard Steadman's clinic in the USA. Sporting director Matthias Sammer assured the defender: "Of course we'll give him all the time he needs to get fit again. We're optimistic. I'm sure he'll be back stronger than ever."
