"We are patient with young players," Ferguson told reporters. "We were patient with Tom Cleverley, sent him on loan on four different occasions until he matured and now he is an important member of the squad.
Speaking about Welbeck's performance in Madrid, Ferguson added: "That performance won't do him any harm, that's for sure. But it's a great boost to younger players who are coming behind him, from the academy as Danny has done.
"He has been with us since he was nine years old and it's a great testimony to the development we do with our younger players. They can see that by trusting us to map out their careers and help them, that they can get to Danny's situation."
United are currently leading the Premier League by 12 points.
