The 29-year-old has been linked with a January transfer window move to Real Madrid.
“I cannot say anything, but it seems hard to believe that players of this level can be exchanged in mid-season,” Caliendo told Tuttomercatoweb. “These players are usually the subject of very well-planned transfers.
“Cases as as Ronaldinho are rare, where he wishes to return home and play. I don’t exclude anything, as football has become a rapidly developing sport.”
