"Over the last 20 years, I have experienced, helped shape and negotiated many negotiations in football. I have to say that when the yes was there, it was the easiest. Not because we offered him an unbelievable financial package, on the contrary," he said on Welt TV. "We spoke about the financial side for 20 seconds because he said he was up for the task. I hope he doesn't hear that now, because then he'll think that he and his agent negotiated poorly. But no, financially it took 20 seconds. When the yes was there, it was one of the easiest negotiations I've had in 20 years."
