Croatia Beat Nigeria 2-0 in teams' first match at FIFA World Cup. Modric, who was named the best player of the game, scored the second goal of the match from the penalty spot in the 71st minute.

"Irregardless of Argentina's result earlier today it was important for us to start the tournament with victory," Modric said.

"We won and now we're gaining confidence. We have a very difficult game ahead - against the group's favorites, Argentina. They need to win to gain points after drawing with Iceland. But, I think, we'll get the points."

Croatia will next face Argentina on Thursday, while Nigeria will take on Iceland on Friday.

The 2018 FIFA World Cup kicked off on Thursday and will continue until July 15, with the matches set to be played in 11 cities across Russia.
