Well its kind of true that PAF is not interested in Rafale. It was from the mouth of ACM Sadaat. Now your seeing these kind of reports that because PAF is trying to spread the word that we are actually "looking" for advanced aircrafts so offers come into their way. Like Charger said PAF did went there evaluate but Rafale didn't impress them much I dont know what is the reason behind it. Is it the reason that Rafale can't act as a multirole aircraft as of now or was it the price.
I think the most realistic and cheap option for the PAF would be to go for J-10. Get it equipped with the western avionics, better radar possibly AESA or PESA.
