Maguire, 18 came through the youth ranks at Bramall Lane after staring in last seasons Academy side which lost to Manchester United in the FA Youth Cup Final over two legs.
Newcastle United have been watching the defender since the beginning of the season and it is believed that he is valued a £3,000,000 for the talented youngster. He signed a new four year deal with the club last November, keeping him contracted at the Lane until 2015. Fulham's new interest in the player could spark a bidding way between the two clubs.
The sale of any of United's young stars could turn United into a new 'Wimbledon' with Manchester United and Arsenal targeted to pay £3,000,000 for Academy keeper George Long - also a losing finalist in last years FA Youth Cup; whilst there is also a rumour that defender Matthew Lowton (also a product of the Blades Academy) is on the verge of a £2,500,000 transfer to npower Championship side Birmingham City.
The club already saw striker Jordan Slew leave for Blackburn Rovers in a £1,000,000 deal earlier in the season. A huge cash investment of possibly £8,500,000 could be what the club needs but would it be a good thing to sell off our young talent?
