Manchester City have asked Heerenveen to name their price for striker Afonso Alves.
The centre-forward, who made his debut for Brazil against England last June and earlier this month scored seven goals in one match against Heracles Almelo in the Dutch first division, bagged 34 goals last season and finished second only to Francesco Totti in the Golden Boot award for Europe's top scorer.
Alves, 26, is in dispute with his club and, like Carlos Tevez, his economic rights are owned by Kia Joorabchian.
