David Moyes singled out Wilfried Zaha, Jesse Lingard and Adnan Januzaj for special praise during the club's pre-season tour.
Ferdinand told the Mirror: "Zaha was really good. He's a new signing and he was one of the better players on tour for us.
"The best players were the young lads: Wilf, Jesse Lingard and Adnan was silky - he set up a great goal in one of the Japanese games.
"Jesse was top scorer on the tour and from left midfield shows what a quality player he is. They were three plus points on the tour and hopefully this season we'll see some more of them.
"The manager would have assessed the squad before, been aware of them as the two boys were here already but Wilf had just arrived.
"The two lads trained with us last season, Jesse came on tour with us last year so we were more than aware how good the players are."
