Pogba admitted he had mixed feelings when he replaced Ryan Giggs at half-time at Leeds.
"I was nervous but so happy to be among players like Carrick, Berbatov and Owen," he said. "It was a nice taste of the first team and made me want even more."
Pogba arrived at United from Le Havre in a much-discussed move in 2009 and was a key figure in the Under-18s' Youth Cup triumph in May.
"We continued a Mancunian tradition by winning that trophy for the 10th time. This proves I'm not in the north of England by accident!"
