The Champions League finalists have reportedly reached an agreement in principal to sign the Ghanaian on a four-year contract.
Italian media outlet Calciomercato has reported that Juventus have agreed a deal with Cagliari to sign Ghana U-20 midfielder Godfred Donsah this summer.
Rumours rifing on Thursday suggest that the Cagliari midfielder has been purchased by the Bianconeri, and will be sent out on loan next season to develop.
According to the report, Juve have agreed a €6 million fee for Donsah, and have reached an agreement in principal to sign him on a four-year contract.
English Premier League side West Ham were earlier this week, keen on signing the 18-year-old midfielder as a replacement for Alex Song.
