Lionel Messi ended an eight-year wait for a World Cup goal on Sunday as Argentina edged past debutants Bosnia at the Maracana stadium in Rio de Janeiro, while fellow No. 10, France's Karim Benzema, put two past Honduras in a man-of-the-match display.
The goals continued to rattle in across Brazil. France cruised to a 3-0 victory in Porto Alegre, and in the other Group E match, Switzerland came from behind to beat Ecuador 2-1 with a dramatic, counter-attacking winner in injury time.

His side recovered from the shock and began to look the better team, but a lack of composure in front of goal saw several long-distance efforts fly high and wide.
Messi's successor as World Player of the Year, Cristiano Ronaldo, expects to start for Portugal against Germany in the pick of Monday's matches.
The 29-year-old said he was fit for the Group G encounter in Salvador, despite struggling with tendinosis in his left knee.
Asked whether a great World Cup was all that was missing from a glittering career, he replied: "I don't think I have to show anyone anything. If you look at my statistics and my resume... I have no words for that question.
