Andrea Pirlo admits Juventus players couldn't believe Manchester United allowed Paul Pogba to leave.

Juventus acted fast to snap up Pogba in 2012 when his Old Trafford contract expired.

"I have played with some great young players, but Pogba was the best young player I have ever seen," Pirlo, now with New York City FC, told the Daily Mirror.

“We saw from his first training session with Juventus that he was special.

“There was a disbelief among the senior players that Manchester United had allowed him to leave."
