Portsmouth have signed free agent Keshi Anderson after the 30-year-old English-Nigerian winger was released by Birmingham City. Anderson, who had not played since New Year's Day, left Birmingham by mutual consent last week and has agreed to an 18-month deal with Portsmouth. According to BBC Radio Solent's Andy Moon, Portsmouth were admirers of the player and his unexpected availability facilitated the move. Portsmouth boss John Mousinho told the club's website that they acted quickly to sign Anderson once he became available, adding that he is a talented winger with the Championship experience they were seeking. The player has a current Transfermarkt market value of €600k, and Rotherham United had also been linked with his signature.
