As it stands now every information about Ronaldo's transfer is just a rumour and should be regarded as false information. This is because many information has been viral on the social media about Ronaldo for how many months now. This is what the journalist do in order to keep their business alive. even Ronaldo as of now does not know where his next destination will be. I think he is more focused on the World Cup, immediately after the World Cup Ronaldo will have a clue on where his next destination will be.
Can yes can no, I think they have a strong network to ensure the legitimacy of a news they will release. in particular, Fabrizo Romano who has a reputation as an A1 football journalist when it comes to player transfers. for example, Ronaldo, who is currently focusing more on his attention on this world cup championship, doesn't mean he doesn't know the current developments related to his future career. at least, Ronaldo's agent "Mendes" who worked behind the scenario regarding contractual matters related to Ronaldo.
whether it's true or not, as far as the news I've read there hasn't been a single statement that came out of Ronaldo or his agent agreeing to a contract agreement with an Arab club. on the contrary, Fabrizo Romano also said that Ronaldo is currently more focused on the world cup. after that, he will only think about his future. so, let's just wait.
