UEFA president Michel Platini has claimed that Franck Ribery will be punished if he does not answer his country's call to play for France.
The Bayern Munich winger sat out Les Bleus' World Cup campaign with a back injury, before calling time on his eight-year international career last month.
France are the host nation of Euro 2016, and Platini has warned his compatriot that refusing to represent his country could have negative implications on his Bayern career.
"I have zero understanding of this," Platini told Bild. "It is not the decision of the players, whether they come to the national team. This is the decision of the coach.
"Ribery cannot simply decide whether he plays for France or not. If coach Didier Deschamps invites him, he must come to the national team.
"This is defined in the FIFA statutes. If he does not come, he is suspended for three games with Bayern Munich. I don't understand him anyway. He is French, the European Championship in 2016 will take place in France."
Ribery has struck 16 times in 81 appearances for the French national team after making his debut back in 2006.
