The agent of Juventus midfielder Paul Pogba doesn't know why Manchester United allowed him to leave.

Mino Raiola orchestrated Pogba's controversial move to Turin in the summer.

"I don't know what Sir Alex Ferguson may have thought on Saturday," Raiola said. "Maybe he underestimated his mental strength.

"When Paul understood that he wasn't being enhanced, he decided that it was over in Manchester. He felt that a move away would do him good."

Pogba was fielded as an alternative to Andrea Pirlo at the weekend, but his versatility allows him to be used in a variety of ways.

"He can play instead of Pirlo, but also as an inside midfielder or even as a centre-back at the end of his career like Frank Rijkaard.

"He has great tactical awareness. And what he is doing at Juventus is thanks to Conte who isn't scared to play youngsters."
