Young has one year remaining on his contract at Old Trafford, and left Villa to join United for £18m in 2011. The Daily Mail have reported that Villa are monitoring developments with the England international at United.
Young joined Villa from Watford for £8m back in 2007, and scored 30 goals in 157 appearances for the Villans.
Villa have money to spend after selling Christian Benteke to Liverpool for £32.5m this week.
"I want to be the best and I want to reach the best of myself,” Benteke said after the deal was concluded. “I came here to win trophies. I came here to reach some great goals with the team.
"It was the right club for me because I had a good chat with the manager and I wanted to be part of his project."
