Cristiano Ronaldo has threatened to leave Al-Nassr in the summer as he continues his strike action against the club, CBS Sports reports. The Portugal superstar missed the 1-0 win over Al-Riyadh in protest at PIF's decision to transfer Karim Benzema from Al-Ittihad to Al-Hilal.

Karim Benzema has ignited a storm in the Saudi Pro League by branding his new club Al-Hilal the "Real Madrid in Asia" immediately after completing a controversial transfer from rivals Al-Ittihad. While the Frenchman eyes more silverware, the move is said to have infuriated Al-Nassr star Cristiano Ronaldo, who reportedly attempted to block it.

Cristiano Ronaldo has not left Riyadh and continues to train with Al-Nassr, debunking reports of a strike. The Portuguese legend remains furious over the club's lack of transfer activity and the controversy surrounding Karim Benzema's proposed move to Al-Hilal, but a return to his homeland has been ruled out as he eyes the MLS or Europe for his next step.

Three years ago, Cristiano Ronaldo stunned the sporting world by joining Al-Nassr. Six months later, the Portuguese trailblazer was joined in the Saudi Pro League by a number of high-profile players, including Karim Benzema, Neymar, Roberto Firmino, Sadio Mane and Aymeric Laporte. Some of those superstars were clearly past their prime, but the mere fact that they were willing to move to the Middle East felt significant.

Mohamed Salah has reportedly emerged as Saudi Pro League side Al-Ittihad's number one priority to replace Karim Benzema. The Egyptian has long been a target for Saudi Arabian clubs and has endured a disappointing campaign so far, hitting out at Liverpool in December before jetting off to the Africa Cup of Nations. The 33-year-old signed a new contract with the Reds last April but his future is up in the air having only scored six club goals this season.
