West Bromwich Albion have made an enquiry for Matt Mills, skysports.com understands.
The highly-rated Reading defender has been at the Madejski Stadium since 2009, when he was snapped up from Doncaster.
The 24-year-old former Manchester City man has continued to impress with Reading since his move to Berkshire.
Now a number of Premier League clubs are thought to be keeping close tabs on him.
And now skysports.com can confirm that West Brom have made an enquiry.
However, with Reading sitting just two points off the Championship play-offs it remains to be seen if they would consider selling one of their prized assets.
