The German told reporters at the Magenta TV World Cup team presentation in Munich: "If Real Madrid had phoned, we would have heard about it by now.
"But that's all nonsense. They haven't called even once, not once. My agent is there, you can ask him. They haven't called him either.
"Right now I'm not thinking about that, luckily there's no reason to.
"For my age I'm quite advanced in life, but as a coach I'm not completely finished. I haven't reached retirement age.
"Who knows what will happen in the coming years? But there's nothing planned."
