Renato Corsi says such an arrangement would also suit Palacios.
He said, "We will meet with people from Madrid. They are very interested.
"They also assured us that they would meet with River after the match (Copa Libertadores). We talked to Madrid because Palacios wants to stay until June with River."
Palacios will face Boca Juniors tonight in Madrid for the second-leg of the Copa.
