Arteta character is difficult to agree with Ronaldo and in fact, I don't think so. There have been quite a few rumors after Ronaldo status as a free transfer that other clubs are after, but from all the lists of these clubs, I don't think anything is certain for now. The Saudi Arabian club has set a price, so which club is really suitable when they are not young anymore and almost players of their age have long retired. Back in the Premier League but even Chelsea have had problems with Graham Potter, and so far Graham Potter has shown no interest in Ronaldo.
There is very little chance of Cristian Ronaldo joining The Gunners, Arteta did not include Cristian Ronaldo in the next winter transfer market target to strengthen his players in the second half of the season. Rumors are circulating, Arsenal are happy to monitor Inter Milan player Hakan Calhanoglu to strengthen the Gunner's attack line, if you look at the developments currently circulating, Arsenal need Hakan Calhanoglu more than Cristian Ronaldo.
The most likely option is for Cristian Ronaldo to go to Chelsea, even if the Club's owners reach an agreement with coach Graham Potter or another option is to go to Al-Nassr, although there is no clarity regarding his future, because all decisions rest with Cristian Ronaldo, who is currently a transfer-free position.
