The 20 year old has become one of the most sought after players outside of the Premier League after breaking into the Leeds first team two years ago.
He has gone on to make eighty-one appearances for the club in all competitions, the last of which coming in Saturday’s season opening defeat to Millwall.
Southampton had a £4.5m bid for the England U20 international rejected by Leeds owner Massimo Cellino while their North East rivals have seen a similar offer shunned.
Byram has informed the Yorkshire club of his desire to move on to pastures new, with Sunderland his preferred destination.
Leeds will hope to bounce back from their loss at the weekend when they turn their attention to their Capital One Cup first round clash with Accrington tomorrow evening.
