Heerenveen striker Afonso Alves is furious with management over their price for him.

Middlesbrough are among clubs chasing the Brazil international, who is upset with Heerenveen demanding over £6 million for his transfer.

Alves has been critical of Heerenveen on his personal website and made it clear he wants to leave before Friday's transfer deadline.

"I don't know what's happening, I know from my agent Roberto Tiburcio, that the club received offers that are over three times what they spent bringing me from Malmo FF one year ago," said Alves.
