English winger Keshi Anderson, 30, has become a free agent after his contract with Birmingham City was terminated six months early by mutual agreement. Football League World has identified Rotherham United, Charlton Athletic, and Portsmouth as clubs that should be aware of Anderson's availability for a potential free transfer. Rotherham is a League One side seeking attacking reinforcements. The club is currently in the relegation zone and is one of the division's lowest-scoring teams. The club has also been linked with another free agent, Duncan Watmore. Anderson is versatile and can play on either wing. Capology estimates the player was earning £5,000 per week at St. Andrew's. His current Transfermarkt market value is €600k.
