The German side have a key relationship with auto giants Audi, who owns an 8.33 percent stake in the club. First-team players are expected to drive their company cars to and from their their Sabener Strasse training base. But Coman is the latest Bayern star to flout this rule - and faces the wrath of his club. The 23-year-old drove in his £174,000 McLaren 570S Spider. Philippe Coutinho and Niklas Sule had previously stirred the pot, by being spotted in their Mercedes and Ferrari motors respectively. This had lead to sporting director Hasan Salihamidzic threatening to fine stars £43,500 for ignoring the rules. A part from Audi, other VW group vehicles, such as Bentleys or Porsches would be acceptable. And while no fines have yet been announced, Coman has made a public apology - blaming a "broken wing mirror" for the mishap. He told Bild: "I would like to apologise to the club and Audi for not having come to training in my company car. "The reason was a damaged wing mirror on my Audi. Still, that was a mistake, of course I can see that. "As a reparation, I will visit the Audi plant in Ingolstadt for an autograph hour as soon as possible and bring some attention to the employees.
