The Addicks, who sit sound at the bottom of the Premiership, have apparently had an audacious bid for the Sunderland star turned away - as well as being told to forget about making any other attempts to prise the former-Oxford United player away from Wearside.
In my opinion, I don't see why any player would leave on-the-up Sunderland for almost-certain-to-drop Charlton - that's if they care at all about their career.
