The Blades announced a week ago that former chief executive Winter would be returning for a second spell at Bramall Lane.
He heads the football club's slimmed down three-man board alongside director Scott McCabe and chairman David Green in a reshuffle aimed at attracting new investment, money which would be ploughed straight into the first team.
Winter told United's official website: "Basically the club has a tremendous infrastructure and a lot of money has been spent over the years in putting such facilities in place.
"In order for someone to acquire this club and all its real estate would take a real considerable amount of money. But if investment arrives it will be to support first-team operations, from there we could scale our model accordingly.
"When I originally joined the club we had a sizeable squad and created a financial model that wraps around the football side, dependent on divisional status. Over a period of a time you have to transition into that working model, if investment arrives we could scale up.
"There are always people interested in football clubs; in my first year here we had a lot of people purporting to have a real interest. The recent re-organisation (of the football club board) makes the proposition a lot simpler."
