Lionel Messi was on target as 2022 world champions Argentina turned on the style to beat Canada 2-0 on Tuesday and reach the Copa America final where they will look for a third straight major title.

The 15-times Copa champions produced their best display of the tournament in front of a capacity crowd at the 82,500 MetLife Stadium in New Jersey.

Argentina soaked up some early pressure before Julian Alvarez ghosted in between two defenders to open the scoring with a tidy finish in the 22nd minute.

Messi had chances throughout the match and doubled the lead in the 51st minute when he stuck out a boot to divert Enzo Fernandez's shot from the edge of the area past Canada goalkeeper Maxime Crepeau.

"The truth is that it's crazy what this group has done, what the Argentina national team has been doing," Messi told TyC Sports after his first goal of the tournament.

"It's not easy for us to be in a final again, for us to compete again to be champions. I'm living it like I lived it in the last Copa America, in the last World Cup."

"These are the last battles and I'm enjoying them to the maximum," said the 37-year-old.

The defending Copa champions will face the winners of Wednesday's semi-final between Uruguay and Colombia in what will be a highly anticipated final in Miami on Sunday.

Canada, who surprised many by reaching the last four in their first Copa America appearance, can take great credit for their run in the tournament but Messi and company were simply a step too far.

"I think the tournament caught up with us a little bit," said Canada's American coach Marsch, who said he noticed that his players looked tired midway through the first half.

"Eventually the physicality and fatigue can catch up with you and that was a big part of what happened with us tonight," he added. (Agencies)
