20-year-old Mills has only made one appearance this season in the Premiership and this coming in City's 4-0 defeat to Wigan Athletic.
The Swindon born defender signed for Southampton after impressing at school level. He signed scholarship forms for the south coast club back in July 2002 along with his brother Jonathon.
During season 2002/03 Mills was part of the Saints U-19 team that became national champions. Southampton then loaned him to Bournemouth and Coventry to get more experience, before Manchester City came in for the England youth international in the January 2006 transfer window. At that time City paid Southampton £250k for the youngster who had been reccommended by former Saints boss and now City assistant Steve Wigley who had managed the youngster at academy level.
The 6'3'' defender made one appearance for City in 2005/06, coming on for namesake Danny Mills in the 2-0 defeat to Chelsea at Stamford Bridge in March 2006.
Could this mean a certain player moving in the opposite direction along with some cash in the deal or just a loan move for the youngster?
