Ferguson rates Scholes even ahead of United legend Bryan Robson.
"Bryan Robson was an unbelievable player," said Ferguson. "Unfortunately, when I came to the club he was 31. I wish I'd had him when he was 21.
"Roy Keane was a different kind of leader. He led by example whereas Robson managed the team on the pitch.
"But you cannot beat Scholes as a footballer. He is an unbelievable player and will always be considered one of the best of all time here.
"We don't lack leadership in terms of the philosophy of our game."
