Argentinian great Diego Maradona has fired a word of warning to his countrymen as they prepare to take on Chile in Sunday's final of the Copa América Centenario.

Argentina booked their place in the tournament decider with a 4-0 victory over the United States as Lionel Messi became the nation's all-time leading scorer.

The Albiceleste are out to clinch their first continental title since 1993, but come up against the same side that beat them on penalties in last year's final.

And former Argentina player and coach Maradona, who captained the team to World Cup glory in 1986, told C5N on Wednesday: "Of course I think we'll win."

However, he also had a message for Gerardo 'Tata' Martino's men ahead of the clash at the MetLife Stadium: "But if you don't win, don't come back."

Meanwhile, on the 30th anniversary of his famous solo goal against England at Mexico '86, Maradona looked back on the strike.

"[England defender Terry] Butcher gave me a real big kick," he recalled. "But when I saw the ball going in it stopped hurting right away. It was a dream goal."
