Afonso Alves wants Middlesbrough move to escape racist abuse
The News of the World says the Brazilian striker, 27, is poised to join Boro in a £10million deal if he is granted a work permit.
Alves is keen to leave Heerenveen after a race row.
He was labelled a "little monkey" by fans and refused to attend a club function.
A spokesman for Alves slammed supporters for being "motivated by Nazi hallucinations."
