Rupia has scored 15 league goals for Nzoia Sugar, just two shy of the 2017 total tally by the Golden Boot winner, Masoud Juma.
According to sources within the club, AFC Leopards called up a meeting with Rupia to convince him to switch allegiance.
The meeting could also throw into doubt a possible move to Zambian side Power Dynamos, who are also interested in his signature, though they are yet to make a formal offer.
Goal now understands that Ingwe can convince the free-scoring striker to cross over to The Den.
AFC Leopards have already signed two players among them Eugene Mukangula and Saad Musa, both from Thika United.
