Fergie defended his youngsters who he made up his team in the 1-0 defeat to Besiktas at Old Trafford last week.
“We’ll pick the same players who played against Besiktas last Wednesday, despite the criticism they got,” said Sir Alex.
“I couldn’t believe that. I played six players, two 18-year-olds, a 19-year-old, a 20-year-old and two 21-year-olds in a European game and you say there’s no future for them.
“It’s unbelievable. When David Beckham, Nicky Butt, Paul Scholes and all those lads made their debuts as a group, they were 22 years of age, three years ahead of these players.
“The young players here now will grow from the experience of last Wednesday.
“I was confident in playing them, they had every right to be played and they will play on Tuesday against Tottenham.”
“Experience is the one thing we have to give the young players,” said Fergie. “The one thing we can’t give them is that old head.
“They got anxious in the last third of the field against Besiktas. They had good chances but hurried things, which is not the biggest crime in the world.
“We’re not talking about ability here, we’re talking about just a bit of experience. That’s why we have to play them.
“They’re stacking up, these young players. We have a lot of them who need to be challenged, and I thought they did OK. I have their futures well mapped out I think.”
