Rennes want answers from misbehaving pair
Rennes general manager Pierre Dreossi has asked Yann M'Vila and Chris Mavinga to explain their behaviour while on international duty.
The duo and Antoine Griezmann (Real Sociedad), M'Baye Niang (AC Milan) and Wissam Ben Yedder (Toulouse) went out in Paris on the eve of their European Championship qualifier with Norway.
France under-21s went on to lose 5-3, thus ending their hopes of qualification, and Dreossi plans to meet his players on Friday to hear an answer for their behaviour.
He told the club's website: "This can't be tolerated. We mustn't let this go. We will meet to get an honest explanation because this is a lack of respect for football, for the team and also for Rennes."
Noel Le Graet, the French Football Federation president, has confirmed to radio station RMC that an investigation is underway into the incident.
Former Lens and Auxerre coach Guy Roux has been particularly damning in his response to the situation.
"It's a total disgrace. They slammed all the values, values of the games togetherness and patriotism," he said.
