The Argentine is widely said to be in direct competition with the Spain goalkeeper for this year's Ballon d'Or after the 31-year-old led both club and country to success."I have had a lot of luck being able to score a lot of goals in Clasicos, which are always great games," he told reporters.
"I am pleased because Iker is one of the best in the world. He is a great keeper. Sometimes, when games are about to start, I just tell myself to score goals."
Barcelona and Real Madrid drew 2-2 in their most recent clash, although the Catalan outfit top La Liga with nineteen points, which is eight more than the capital club who sit in sixth.
