Higuain has been in stunning form this season and has scored 16 goals in 18 appearances for his club. The youngster, who nabbed a brace last weekend, also notched the only goal of the game for Argentina in their midweek victory over Germany.

And Higuain, who was just 19 when he signed for Madrid, believes some of the credit for his goalscoring prowess must go to Van Nistelrooy and his words of wisdom.

"Ruud told me that goals are like ketchup," he told La Sexta. "Sometimes as much as you try, they don't come out, and then they come all of a sudden."

Speculation was rife in the summer that Higuain was set to leave Madrid after they splashed out on the likes of Kaka, Cristiano Ronaldo and Karim Benzema, with Manchester City, Chelsea, Juventus and Inter Milan said to be among the interested parties.

The Argentina international, who was the club's top goalscorer last season, is well on course to take the Pichichi trophy - awarded to the Primera Division's top scorer.

Madrid are said to be keen to offer Higuain a new deal which would see him receive a salary hike, putting him on a par with the likes of Benzema, and the 22-year-old is hoping to sign on the dotted line soon.

"I hope we can reach an agreement as soon as possible," he added. "But my family and agent are dealing with that.

"I'm dedicating myself to playing football, which is what I most enjoy."
