Speaking to Sport Bild, Undav said: "Everyone under the sun has spoken out about Nick; podcasts have been made by people you've never seen before. Experts have spoken out, every day. Just leave the boy alone; at some point, enough will be enough. If the issue hadn't been made so big, it wouldn't have been so bad for Nick. It was on Nick's mind, so I don't need to talk nonsense.
"He didn't act angry or train less well. Sure, he laughed less, was a bit more withdrawn. Now the whole thing is over, everything's been resolved. And after this decision, he seems more relaxed to me – outwardly – again. In the locker room, he was always the same.
"[Bayern Munich] is the biggest club in Germany, one of the biggest clubs in the world. Nick wanted to take his next step; he's still young. Of course, that's understandable."
