Middlesbrough midfielder Fabio Rochemback is keen on a move to Benfica.
"We are interested in this subject," Rochemback Snr told O Jogo. "Fabio's desire is to play in Benfica and I do not believe there is any problem between Middlesbrough and Benfica for a deal.
"Now the decision is from the English (Middlesbrough).
"My son has received with enthusiasm this offer because he desires to play in a big club like Benfica.
"He has played for their rivals Sporting, but he is professional and is able to triumph in any club.
"Also it is very important that he knows coach Fernando Santos."
