Cristiano Ronaldo said Portugal must strive to improve at the World Cup after yesterday's 1-0 win over Group B rivals Morocco left them within sight of the knockout rounds. The Real Madrid forward scored his fourth goal in two games in Russia as the European champions moved top of their group ahead of Spain's match against Iran.

The Real Madrid star struck in the fourth minute in Moscow to surpass Hungarian legend Ferenc Puskas as Europe's all-time leading scorer with 85 international goals. "I'm very happy. The most important thing was to win the game and to get the three points," Ronaldo said after his fourth-minute strike in Moscow decided a hard-fought contest. "We knew if we lost we could be out. We knew Morocco would be giving their all. It was a surprise at the start because they were so strong. I managed to score a goal, it was great for me."
