Milan, 20 March (LaPresse) – A hamstring injury will keep Cristiano Ronaldo out of Portugal’s friendlies against the United States and Mexico ahead of the World Cup in North America. The 41-year-old Ronaldo has not played since 28 February, when he limped off the pitch during the Saudi league match won by Al-Nassr against Al-Fayha 3-1. As expected, Portugal manager Roberto Martínez did not include the five-time Ballon d’Or winner in the squad announced on Friday. Portugal will face Mexico in Mexico City on 28 March, before taking on the United States in Atlanta on 1 April. Ronaldo holds the record for the most goals in the history of men’s international football with 143 goals for Portugal. The World Cup kicks off in June.
