Transfer rumours: Sunderland's rivals to conclude £500k deal - Bristol City, Charlton, Portsmouth and Bolton and Nottingham Forest talk

The attacker is said to be close to agreeing a January move to Sunderland’s rivals in League One for a fee of £300,000.

Charles has been in a contract dispute with his club, which has seen him limited to nine appearances this season.

The player’s last outing came back in September but a number of clubs have been linked with the Northern Ireland international including Bristol City and Nottingham Forest.

Charles bagged 20 goals last term but Alan Nixon of The Sun has claimed that Bolton are close to securing his signature.

He was also believed to be the subject of a bid from an unnamed third-tier side last season but Rotherham opted to reject the approach.

Sadlier has been used on an on-off basis by Rotherham in League One this season after sustaining a serious ankle injury last campaign.

The winger has been limited to just five league starts during the current season but has impressed for Rotherham United in the Papa John’s Trophy.
