Ronaldo: Hành trình World Cup của Bồ Đào Nha 'còn dài'

Cristiano Ronaldo defended Portugal 's performance against Congo DR in their World Cup opener but is already looking ahead to the next game.

Portugal dominated possession but had just one shot on target in Wednesday's 1-1 draw in Houston .

"Nothing was lacking," Ronaldo, 41, told reporters after the game. "That's football. Portugal could have won, but they could also have lost."

Ronaldo, who joined Argentina captain Lionel Messi as the only players to appear in six World Cups, played all 90 minutes on Wednesday.
