Sheffield United have reportedly warned the clubs chasing Harry Maguire that they will have to come up with a huge bid to prise him away from Bramall Lane this summer.
The 19-year-old centre-back, who has made 61 first-team appearances for the Blades, is understood to have attracted interest from Leicester City and Watford.
United have decided to reject all bids for the player unless they are on a par with the undisclosed seven-figure sum that Aston Villa paid for Matthew Lowton earlier this month, according to the Sheffield Telegraph.
It is understood that United are yet to receive any bids for Maguire.
