The 29-year-old, who began his career with the Brazilian outfit, has been widely tipped to leave his current club AC Milan at the end of the current campaign.
Should those reports prove to be correct, Rodrigues has conceded that Santos would be keen to secure the former Manchester City striker's services.
"Regarding Robinho, we'll talk again in the next transfer window," he told Lancenet. "We'll contact him as soon as the window opens again."
Robinho left Santos in 2005 when he joined Real Madrid.
