The rivalry between Lionel Messi and Cristiano Ronaldo dominated football for more than a decade and today the world will have the opportunity to see another confrontation between the Portuguese and the Argentine.
After 20 years in Europe's top leagues, Ronaldo now plays for Saudi Arabian side Al-Nassr after his contract with Manchester United was terminated and ironically his first match in the Middle East will be against the rivals his century.
Messi's Paris St Germain will face a combined Al Hilal-Al Nassr team in a friendly, giving Ronaldo and Messi a chance to rekindle their old 'El Clasico' rivalry when they played for Real Madrid and Barcelona.
