Borussia Dortmund coach Jurgen Klopp has warned Mario Gotze that he is making a mistake in joining Bayern Munich.
The Germany international playmaker will leave BVB and move to the Bundesliga champions this summer.
"It's absolutely normal that people go different ways," Klopp told The Guardian. "At 18 I wanted to see the whole world. But I am only in Mainz and Dortmund since then and it's not the middle of the world. It's OK that they want to go to different places. But they get there and, shit, it's not the same.
"Look, you work for The Guardian, and sometimes you see your colleagues and think: 'Oh no, the same old thing every day.' Maybe you want to go to The Sun? More money, less work. More photographs, [fewer] words.
"It was like a heart attack. It was one day after [we beat] Malaga. I had one day to celebrate and then somebody thought, 'Enough, go back down on the floor.' At our training ground [general manager] Michael Zorc walked in like somebody had died. He said, 'I have to tell you something. It's possible that...'"
Gotze is currently struggling with a hamstring injury and is doubtful for Dortmund's Champions League final against Bayern Munich at London's Wembley Stadium on Saturday.
