The 18-year-old was introduced for his Barclays Premier League debut in United's win over Stoke on Tuesday as Ferguson opted to give Pogba some valuable experience.
And Ferguson admitted he was impressed with his performance, telling the BBC: "Pogba did very well."
It was a notable move on the day Ravel Morrison quit for West Ham and comes at a time when United are still trying to persuade Pogba to sign a new contract.
Italian giants Juventus are among the clubs who have expressed an interest in the French teenager, whom Ferguson has previously advised not to follow the money trail because if he makes it at Old Trafford, Pogba will be a very wealthy young man.
The United boss confirmed talks were continuing and he was hopeful of a positive resolution.
"The boy has great talent and tremendous physique for an 18-year-old," he said. "You can't believe it.
"We are negotiating his contract at the moment.
"It is a bit complicated at the moment because he has changed his agent a couple of times.
"But the boy wants to stay, that is obvious. Hopefully we can get it done soon."
