Lionel Messi will not let his goalscoring drought affect him as long as Argentina continue to win at the World Cup.

The Albiceleste edged Nigeria 1-0 in their Group B opener before crushing South Korea 4-1. The Barcelona star had plenty of chances to score in both encounters but was denied by great goalkeeping.

"It's not a problem," said Messi. "The important thing is that I had opportunities and although the ball didn't go in, eventually it will."
