Since leaving Lazio for the Hammers in 2018, Anderson has scored 10 goals from 58 appearances in the Premier League.
However, with just over two years remaining on his contract, the 26-year-old is expected to attract admirers during the next window.
According to Corriere dello Sport, Napoli are contemplating whether to make a bid for the Brazil international, whose previous form in Serie A led to West Ham being prepared to pay £40m for his services.
West Ham, who only remain out of the Premier League relegation zone on goal difference, would likely make Anderson available for transfer if they drop down to the Championship. body check tags ::
