Lionel Scaloni was delighted with the application of his Argentina side against Mexico, claiming they played "a perfect game" in a 4-0 victory.

Lautaro Martinez hit a first-half hat-trick as Argentina, still without Lionel Messi, ended Tata Martino's unbeaten start to life as Mexico coach in style, with Leandro Paredes also on target from the penalty spot.

Scaloni's men ceded possession to their opponents at San Antonio's Alamodome, but the coach saw his plan work to a tee and hailed the team's spirit.

"We knew the way that Mexico would play and we came out quickly to create some chances," he told a news conference. "We are happy because we played a perfect game.

"We knew that Mexico would dominate the opening minutes and that's why we were prepared to go out on the counter-attack.

"We gave the feeling that we are a team - that's the important thing. Everyone played for their lives, for their team-mates and for wanting to be in the Argentina team.

"We knew that if we recovered the ball, we would have to get it quickly to the striker.

"It's no good if we just defend well. We analysed Mexico a lot and we were courageous enough to do what we had to do in this match.

"We want an Argentina team that is competitive, where our opponents respect us."

Martinez was substituted at half-time, with Scaloni revealing the striker had been carrying a knock prior to the match, joking the Inter star appeared to play better injured.

"The change was planned, because he had some discomfort," the coach said. "Hopefully he can continue playing with discomfort."
