The World Cup produced three tight games on Wednesday as Portugal, Spain and Uruguay won but once again the favourites failed to shine. It was three of the world's top marksmen who did get on the scoresheet, though, as Cristiano Ronaldo and Diego Costa continued their fight for the Golden Boot, while Luis Suarez scored in his third World Cup. AFP Sports looks at three things we learned today at the World Cup.

Ronaldo eyes more gold Few goalscoring titles still elude Ronaldo and he may soon have one more to add to his collection after netting for the fourth time in two games against Morocco to move out in front in the race for the World Cup Golden Boot. Ronaldo has now already scored more goals in Russia than his three previous World Cup campaigns. Having spearheaded Real Madrid's run to a third consecutive Champions League, Ronaldo's fast start to the tournament also puts him in pole position for a sixth Ballon d'Or -- to finally move ahead of Lionel Messi's five. Messi missed a penalty in Argentina's opener, while fitness issues for Neymar and Mohamed Salah have blighted their challenge to Ronaldo's crown. The competition is not even a week old, but the World Player of the Year's message is clear: "Catch me if you can."
