The R's have been heavily linked with the Portuguese full-back today but chairman Tony Fernandes was remaining calm over the reported signing.
However, manager Mark Hughes has revealed that talks are well underway and a deal could soon be sorted.
"We are having discussions with the boy and his advisors and it is something we are keen to do if we can," he said.
"We think we are very close but hopefully in the next few hours that will be shaped and we will have a better understanding about whether that is possible.
"We think we are very close to being able to bring him in but as usual I don't really like talking about players we haven't signed until we actually do.
"He is the right quality and has a lot of football left in him as well, he is only 29 and we would be delighted if we could bring him to the club.
"I think he now understands what we are trying to do here and that is why players of his ilk are seriously considering coming to Queens Park Rangers now."
