Vogts, now Azerbaijan coach, claims the 27-year-old spent too much time partying.
He snapped: “I am happy that Podolski has left Cologne. He had too many friends in the city.
“He got praised as a great runner if he ever got back to defend three times in a game. He got an easy ride and he believed his own publicity. But now he has a coach at Arsenal in Arsene Wenger who will make him work hard in training as well as matches.
“If Podolski fails to train properly twice or three times he won’t get games. That is the way to develop him into a true professional.”
