Robben hung up the boots at the start of this season after coming off contract at Bayern.
But Botafogo vice-president Ricardo Rotenberg has revealed they're in contact.
"It is difficult, he has not played for a long time and if he wants he can earn four times more elsewhere, but he knows of Botafogo's interest and seemed happy with the call," declared Rotenberg.
"Fábio was exciting and so was Rafael. They are good-hearted," added Rotenberg.
