Pogba's agent slams 'confused' Juventus
The 19-year-old has shown promise in Turin following his arrival from Manchester United.
He had been in contention for a starting place against Pescara before it was announced that he would not travel with the team.
A statement on the club's website read: "Pogba stays behind in Turin after reporting late to training on two separate occasions."
The player's agent Mino Raiola has criticised the Serie A champions for deciding to publicise news of his client's indiscretions.
"Whoever decided to put this news out on the website is evidently confused," Raiola told Gazzetta dello Sport.
"I hope it wasn’t (coach Antonio) Conte’s own decision, otherwise it means he is unable to deal with situations at this level.
"Paul is very disappointed with what happened, both for his lateness – despite good reasons – and for not being a part of the squad.
"In the first instance of lateness he was notified late at night.
"In the second he had some appointments – the club themselves had organised for him to go through some paperwork."
