He was replaced by Nani, the Portuguese winger making his first start since early March, in the only change to the team that beat Aston Villa 4-0 last week in a match where Young won a hotly debated penalty that led to the opening goal.
It followed a similarly debatable penalty decision won by Young in a win over QPR a week earlier and the United player's ability to stay on his feet -- or not -- in the opposition penalty area has become a subject of national debate.
"I've had a word with Ashley," Ferguson said Friday. "He understands where we come from and hopefully it makes a difference.
"The first thing you have to say about last week's incident is that if the player doesn't bring him down he's going to score.
"It's a clear goal-scoring opportunity. He caught him, though he did overdo the attempt to get a penalty kick.
"I'm not sure he actually tried to get a penalty kick but he certainly went down quickly."
Victory for United would mean they could retain their Premier League title at arch local rivals Manchester City a week on Monday.
Second-placed City, currently five points behind United, are in action later Sunday away to bottom of the table Wolves.
