Lionel Messi's Inter Miami will face Cristiano Ronaldo's Al Nassr next February in the Riyadh Season Cup for what could be the final showdown of the global football icons.
Eight-time Ballon d'Or winner Messi, who joined the US squad in July and sparked a championship run in the Leagues Cup against US and Mexican clubs, is expected to meet Ronaldo, a five-time Ballon d'Or winner.
Messi, 36, led Argentina to last year's World Cup crown and has long been a rival of Portugal captain Ronaldo, 38.
Inter Miami was named the guest international side and will join Saudi Pro League sides Al-Hilal and Al Nassr in next February's Riyadh Season Cup, but no exact dates for matches at Kingdom Arena in the round-robin competition were announced.
Miami also features Messi's former Barcelona teammates Jordi Alba and Sergio Busquets who combined for five La Liga crowns.
Ronaldo, a five-time Champions League winner, is joined by former Liverpool standout Sadio Mane and former Inter Milan captain Marcelo Brozovic on Al Nassr.
Al-Hilal features Brazil all-time leading scorer Neymar, who is recovering from a knee injury.
Last January, Ronaldo made his first appearance in Saudi Arabia following his move to Al Nassr with a Riyadh All-Star XI that lost 5-4 to a Paris Saint-Germain side featuring Messi, Neymar, Kylian Mbappe and Sergio Ramos.
