Sammer is unimpressed by the antics of Aubameyang as he pushes to join Arsenal this week.
He wrote for BILD: "One thing, we have to get straight to the point. If a player strikes somewhere, but a big club picks up the striking player - and that's exactly what Jupp Heynckes said - that ultimately it has something to do with decency, morality, and unity.
"This so-called 'rotten apple', who was lazy at a club, but suddenly presents himself in full bloom and beauty at this club, it is wrong.
"Clubs are subject to constraints and the power of money makes them act in constraints, so as not to get themselves into trouble. That is why, for the first time, we have a situation where we feel, on the basis of so much money, how counterproductive this can be in the form and connection to the morality of the employer.
"That is unhealthy."
