Paul Pogba has accused former club Manchester United of "disrespect", claiming he was made to train alone during the contract dispute that preceded his move to Juventus.
The 21-year-old French midfielder left United in July 2012 after failing to agree a new deal.
"They left me out because they said I wanted to leave," he told Football Focus on BBC World News.
"That is disrespect. Maybe they didn't think they were making a mistake."
Pogba himself was accused of a lack of respect when he left United, with then-manager Sir Alex Ferguson telling MUTV he was "quite happy" to see the player leave.
"I don't think he showed us any respect at all," Ferguson added.
Pogba made just seven substitute appearances for United and insists his move was motivated by a desire for more playing time rather than money.
"Manchester United is a big club but you have to think about yourself," Pogba added.
"You have to play. The coach told me there would be space to play, but I wasn't playing. I was training alone for one week."
Juventus won Serie A in Pogba's first season with the club and are on the brink of defending the title.
Pogba has been a key part of their success, scoring 12 goals in 60 league appearances.
His good form has prompted talk of a move back to Manchester, with both United and City rumoured destinations, as well as a £40m switch to French champions Paris St-Germain.
Juventus president Andrea Agnelli said in October that his club would find a big-money offer for Pogba hard to resist.
