Nicklas Bendtner faces a fine from Wolfsburg after posting a photo of himself on Instagram getting into a Mercedes -- rivals to the Bundesliga club's sponsor Volkswagen.
Bendtner, 28, posted the picture on his Instagram account earlier this week, with the image showing him climbing into the car, alongside text saying: "On my way to another session."

The Denmark international looks to have landed himself in trouble with his club, with Wolfsburg director of sport Klaus Allofs stating his anger at the decision to post a photo featuring a rival manufacturer's car.
"We have our rules, one of those being that you must pay attention to how you are photographed in public," Allofs is quoted as saying by Sport1. "The rules are not new.
"It's misconduct and it's careless, which at the end of the day will cost [Bendtner] money."
Bendtner was fined £80,000 by UEFA after displaying underwear branded with the name of bookmaker Paddy Power during Denmark's match against Portugal at Euro 2012.
The striker, who will be out of contract in the summer, has struggled for regular first-team football at Wolfsburg, with head coach Dieter Hecking preferring Bas Dost and Max Kruse as options in attack.
