He had only been fit for three months after suffering a dislocated knee at old club Borussia Dortmund.
He told BILD: “There were times after my cruciate injury that I asked, ‘Why me?’
“In the weeks after the injury you are saying, ‘What have I done so wrong to have something like this happen to me again?’ But thinking like that, I realised, gets you nowhere in the end.
“I just had to accept fate wants to put a few more setbacks against me than others.
“In the end, I have not broken my neck.”
