Kingsley Coman, a Bayern midfielder, will pay €50,000 in fines, writes Bild.
The footballer arrived at the training session in his personal Mercedes car, not Audi.
The security guards thus did not let Coman in the underground car park. The Frenchman left his car on the street.
Munich club footballers are allowed to use cars provided by sponsor Audi and VW Group.
Players must use company cars when travelling to training, games and business meetings.
This rule was announced by Bayern sporting director Hasan Salihamidzic in January.
So, the player will now be made to pay a fine.
