The anticipated reunion of soccer's two biggest rivals failed to deliver Thursday, with Lionel Messi restricted to a late cameo appearance as a substitute and Cristiano Ronaldo watching from high up in the stands as his Al Nassr team thrashed Messi's Inter Miami 6-0.

Ronaldo had been ruled out because of a calf injury and Messi surprised fans in Saudi Arabia by sitting on the sidelines as the exhibition Riyadh Season Cup match kicked off.

The Saudi Pro League club's head coach Luís Castro said Wednesday that Ronaldo would not be able to play in the match because of a calf injury, but Messi's reason for not starting the match has not been officially announced.

There was confusion ahead of kickoff as to whether Messi would be included in Miami's squad at all after the MLS team posted a team sheet on X, formerly Twitter, with his name absent.

However, that post was deleted and a new team sheet that had Messi included on the bench was shared. The fans in Riyadh had to wait until the 83rd minute to see Messi enter the action, by which time Miami was already losing 6-0.

The game, hosted at the Kingdom Arena in Riyadh, Saudi Arabia, had been billed as the final club meeting of the two stars who dominated European football for a decade, most notably during their spells with Real Madrid and Barcelona.

Messi and Ronaldo have faced off 36 times through the years in matches for club and country, with Messi's teams winning 16, Ronaldo's teams winning 11 and the sides settling for draws on the other nine occasions. Messi has 22 goals and 11 assists in those matches; Ronaldo has 21 goals and one assist.

Ronaldo, who has won five Ballon d'Or awards to Messi's eight, watched the match from the stands.

With the Saudi Pro League on its midseason break, Al Nassr planned to play two fixtures in China against Shanghai Shenhua and Zhejiang before the match against Miami in Riyadh.

But Ronaldo issued a public apology on Jan. 23 after his calf injury contributed to Al Nassr's postponement of their tour of the country.

Inter Miami, who lost 4-3 to Al Hilal on Monday, travelled to Saudi Arabia as part of their preseason tour. They are due to face a Hong Kong XI on Feb. 4.
