Bild (as always, take with a grain of salt) is reporting that Ilkay Gündogan's injury, originally thought to be a two-week recovery, will probably shut him down for 2013. His lower back problems have not improved, and there is general confusion at BVB about what the next step should be, with Sport Director Michael Zorc's stating that there is no definitive prognosis.
This latest injury news comes on top of a slew of other Dortmund regulars being sidelined, for various reasons: Sven Bender (muscle issues in leg and lower back), Marco Reus (partial ligament tear in his ankle), Jonas Hofmann (tendon inflamation in the knee), Nuri Sahin (partial ligament tear), Lukas Piszczek (hip surgery), Sebastian Kehl (ankle), Marcel Schmelzer (muscle tear) and Sokratis (adductor strain).
Reus and Bender are only expected to miss about 2 weeks each, so the World Cup Qualifying break comes at an opportune time, but some of the other ones are looking like long term affairs.
It will be interesting to see how well Klopp's system can compensate for some key missing players.
