Pogba made seven appearances for the Reds and it looked like he was the sort of player that could have turned into one of the all time greats at Old Trafford.
But he kept refusing to sign a new contract with the club even though he was offered the chance of more first team games in the coming season, but the Turin giants have been sniffing around and the 19 year old decided that is where he wants to go.
When interviewed by MUTV, Ferguson made his feelings about the player known.
"Pogba signed for Juventus a long time ago as far as we're aware.
"It is disappointing. I don't think he showed us any respect at all, to be honest,"he added.
"I'm quite happy that if they carry on that way, they're probably better doing it away from us."
