Belgium head coach Marc Wilmots has confirmed that Roma attacking midfielder Radja Nainggolan has a habit of smoking.
The 28-year-old is a confirmed target for new Chelsea manager Antonio Conte although he made it clear that he wants to stay in Italy.
He scored a superb goal to help Belgium battle past Sweden on Wednesday and is expected to start when they take on Hungary on Sunday night.
And Wilmots says he is comfortable with the player smoking, as long as he performs on the pitch.
"Yes, Radja smokes," Wilmots told Sporza.
"It's a habit and a lot of people do it in France and Italy.
"I am not going to stop him if that's what he needs. I am flexible when it comes to matters like this. It's his body.
"I'm fine with it so long as he performs out there on the pitch.
"I always make sure he gets a room with a balcony, so he does not set off the smoke alarm.
"I think he is the only one at the Belgium national team who smokes.
"I reckon he would trash his room if we forbade him to smoke five or six cigarettes per day.
"It's his problem if this means he will have to retire at 30 rather than at 35."
