QPR boss Harry Redknapp is making a trip to Portugal for face-to-face talks with Porto defender Rolando.
Both clubs want the deal to happen, but Rolando is reluctant and turned down the Rs for a third time in six months last week.
A Bola says QPR are refusing to give up and have dispatched Redknapp and the club's chief executive to Oporto to meet with Rolando in a final effort to convince him about the move.
