Cristiano Ronaldo headed an early winner as Portugal beat hosts Russia 1-0 in the Confederations Cup on Wednesday to go top of Group A and spoil Russian goalkeeper Igor Akinfeev's 100th cap.
European champions Portugal took the lead when captain Ronaldo headed a precise cross by Raphael Guerreiro past Akinfeev in the eighth minute and then held on as a re-energised Russia created chances in the second half.
