The Frenchman has offered his apologies for his tardiness and has vowed that he will not let it happen again in the future.
The Frenchman was left out of this weekend's Bianconeri squad for the side's Serie A match against Pescara following his tardiness, but the former Manchester United midfielder has stressed that he will learn from his errors.
"I was wrong and I'm sorry for what happened. I apologize because I showed a lack of respect toward my teammates and [heacd coach Antonio] Conte," the midfielder told Tuttosport. "I never had the intention to show up late. That I was late for training was down to some trivial things. I made a mistake."
"I realize that I was wrong though, and I will do my utmost to make sure I do not make the same mistake again. I will not be late again in the future. The matter is closed now as far as I'm concerned."
The 19-year-old has made eight appearances for Juventus this campaign, scoring twice in the process.
