Iran vs Portugal: History awaits

Ronaldo will face former coach Queiroz

SARANSK, Russia - If Iran can be the first team to stop Cristiano Ronaldo from scoring at this year's World Cup, the result could be historically significant.

A final score favorable enough to move Iran into the knockout round for the first time also would carry considerable personal meaning for the Asian team's Portuguese coach, Carlos Queiroz, who was once Ronaldo's coach on their country's national team.
