The agent of Douglas Maicon says he would prefer to pull on a Real Madrid shirt next season rather than an Inter Milan jersey.
Maicon has made it clear he wants to be reunited with Jose Mourinho.
"The issue of figures is a problem the two Presidents have to sort out between themselves," Antonio Caliendo told Sky Sport Italia.
It is reported that Inter want at least 10m more than the 25m currently on offer.
"Massimo Moratti and Florentino Perez are such good friends that I'm sure they are the only ones who can make that decision.
"Of course everyone wants to get the best deal possible from a transfer involving a great champion. I hope that for the good of everyone they can find a middle ground."
Caliendo added: "Certainly today Maicon has more hunger to win with Real Madrid than with Inter."
