Ashley Young will be ready for Madrid game, says Ferguson
The former Aston Villa man did not make it and there have been claims the injury is much more longer term that Ferguson first anticipated.
However, the United boss insisted Young is not far away from a return and will be fit to face Jose Mourinho's men.
"Ashley is not far away," said Ferguson.
"He has done a bit of training and he is on the road back."
Asked whether he would be fit for the Real Madrid games, Ferguson replied: "I am sure of that."
"It has taken a bit longer than we thought but he has done a bit of training too," said Ferguson.
"But the fact we have Chris Smalling and Phil Jones fit is a big bonus to us."
Neville was critical of De Gea's weak punch at White Hart Lane, which led to Tottenham's injury-time equaliser.
That led to claims from TalkSPORT presenter Richard Keys that Neville had been ordered to make the comments, which have been dismissed by all parties.
"I am not getting into that at all," said Ferguson.
"You have to listen to some idiots in the game."
Ferguson also skirted around Rafael Benitez's renewed claims of the Scot having undue influence on the Football Association.
"I am not bothered what Rafa says to be honest," said Ferguson.
"I have more on my mind."
Ferguson last night responded to the FA's demand to offer his 'observations' about post-match criticism of assistant referee Simon Beck at Tottenham.
He will find out on Tuesday evening whether the FA intend to bring a misconduct charge.
However, Ferguson is not entirely convinced the FA will see the matter his way.
"I wouldn't bet on that either. We will see what happens," he said.
