Manchester United are reportedly willing to listen to offers for Anderson.
United manager Sir Alex Ferguson has become increasingly disillusioned by the Brazilian's injury problems and he is ready to offload the midfielder, according to Goal.com.
The 24-year-old has been linked with moves to Tottenham Hotspur and Benfica and it is understood that United are looking to recoup the £18m they paid Porto in 2007.
Anderson made just 10 appearances for the Red Devils last season.
