A second-half strike from Lautaro Martinez gave his side astonishing victory with the striker’s goal moving him into a tie with Diego Maradona as the country’s fifth all-time scorer, according to Reuters report.

Martinez notched his 32nd international goal 10 minutes after the break, capitalising on a fine cross from Lionel Messi to fire home a half-volley into the top-right corner.

"I’m happy because my whole family came and I always want to give my best. This year was very positive and luckily we closed it with a victory," Martinez told local TV.

"It was a spectacular year in terms of performance, goals, games played. We have to keep playing and improving day by day.

"Everyone wants to beat us. Argentina s national team are always the main characters. There are things to improve but we have to continue on this path."

The World Cup holders lead the CONMEBOL standings with 25 points, five clear of Uruguay. Peru are bottom of the 10-team table with seven points after 12 games.

The top six qualify automatically for the World Cup in the United States, Mexico and Canada.

"We are Copa America champions, we are first in the qualifiers. We have to be proud," Argentina goalkeeper Emiliano Martinez said.
