Sergio Ramos, Jordi Alba, Sergio Busquets, N'Golo Kante, Angel Di Maria and Roberto Firmino are also among the seasoned World Cup and Champions League winners being lined up for the Saudi Pro League, the source said.

PSG will take on Saudi side Al Nassr in Osaka on July 25 and J-League club Cerezo Osaka three days later.

Saudi Arabia's Al-Nassr could not resist the temptation to sign five-times Ballon D'Or winner Cristiano Ronaldo in January, but although the prolific Portuguese forward scored an impressive number of goals, they finished the season empty-handed.

Cristiano Ronaldo's comments yesterday that the Saudi Pro League could in time become one of the top five leagues in the world drew plenty of ridicule, but is it so unfathomable that the Middle East could become a centre of world football?

Cristiano Ronaldo revived Al-Nassr's slim hopes of winning the Saudi Pro League title in his first season at the club after scoring a penalty to help them to a 2-0 victory over Al-Ta'ee on Tuesday.

Messi's father Jorge has denied the reports and said nothing will be decided until the end of the season.

Cristiano Ronaldo brought out the fierce competitor in him on Tuesday but his efforts were in vain as Al-Nassr failed to score in two consecutive fixtures in the Saudi Pro League and suffered a 2-0 defeat away at Al-Hilal.
