Despite strong suggestions he could be on his way to Turkey, the 30-year-old's representative, Marisa Ramos, has played down the prospect of the former Real Madrid man joining Besiktas.
"We do not know anything about the possibility of [going to] Besiktas," Ramos is quoted as saying on the Spanish news site Mundo Deportivo.
"At the moment we have not moved anything. There are many hypotheses, we have to wait and see. But with Besiktas, we have not had contacts."
Greek champions Olympiacos, American outfit Orlando City and several unnamed Brazilian teams are also thought to be in the running to sign Robinho.
