Argentina striker Gonzalo Higuain admits he is much calmer heading into the World Cup now that his future at Real Madrid has been resolved.

The 22-year-old looks set to be a Madrid player until 2016 after reportedly agreeing terms on a three-year contract extension, allowing him to focus on the World Cup.

"Obviously I'm calmer now. Now I'm focused 100% on Argentina and thank God I don't have to worry about anything else. I'm at a World Cup, I play in the best team in the world...everything is perfect. Now I need to help my national team," he said.
