Ronaldo moved to the Middle East in December 2022, shortly after his contract with Manchester United was terminated by mutual agreement.

He became the best-paid player in football history with an annual salary of £177m.

However, 10-time league champions Al-Nassr have only won the 2023 Arab Club Champions Cup since he joined.

He signed a new two-year contract last June, but BBC Sport has been told his former Real Madrid team-mate Karim Benzema’s recent switch to league leaders Al-Hilal from Al‑Ittihad was the principle reason for five-time Ballon d’Or winner Ronaldo’s frustration.

Al-Hilal, who sit at the top of the Saudi Pro League table with one point more than Al-Nassr in second, are also run by the PIF.
