Didier Deschamps has warned Ousmane Dembele that he must improve his attitude if he is to get back on track at Barcelona.
The 21-year-old was not in the squad for Barca's shock 4-3 defeat to Real Betis at Camp Nou on Sunday.
"I haven't talk with the staff of Barcelona because I don't interfere in the daily business of clubs," he told a media conference.
"It's their responsibility and it's up to them to manage their players, on and off the field.
"Ousmane has been with us for a while. That's his usual trick to be late, but in his defence, I'm sure he'll say: 'I'm not the only one.'
"Whether at a big club like Barcelona, in the French national team or elsewhere, he has to pay attention to that.
"It's part of the life and requirements of a professional footballer.
"He must improve to prevent it from becoming negative. These are situations that can be repeated. The sooner he understands that, the better for everyone."
