The Argentina No.1 admits playing in Qatar this winter has become such an obsession he’s cut down on social outings.
Speaking to the press in South America, he said: “I don’t even go out for a coffee with friends. If I want to win things with the national team, I have to set my sights high.
“I’m obsessed with my job. I want to be at my best to reach the World Cup.
“In these months, I’m going to achieve it. I want to be the best goalkeeper in the World Cup.”
Martinez, who joined Villa from Arsenal for £20million in 2020, helped Argentina win the Copa America for the first time in 28 years last summer. In January, he signed a new five-and-a-half year deal at Villa Park.
