The 2024 Copa America final was delayed by 30 minutes after supporters without tickets breached security outside the Hard Rock Stadium.

Footage circulated on social media showing fans breaking through one of the stadium's main gates, with police making several arrests while attempting to stem the flow of people.

The gate was subsequently locked down, while supporters were seen receiving medical attention and asking for water in the stifling conditions.

The Copa America's climax between Argentina and Colombia was due to begin at 8pm local time (1am BST), but Copa America confirmed that kick-off had been pushed back.

"We would like to inform you that individuals without tickets will not be allowed entry into the stadium," they wrote on X.

"Only those with purchased tickets will be permitted entry once access is reopened. We also inform you that the match will be delayed by 30 minutes, starting at 8:30 PM [local time]."

Reigning champions Argentina are seeking a record-breaking 16th Copa America triumph, while Colombia target their second title - and first since 2001.

Lionel Messi has warned Argentina's Copa America final opponents Colombia the injury worries that hampered him earlier in the tournament are now firmly behind him.

Messi is looking to lead La Albiceleste to a third major tournament win in as many years on Sunday, as the 2021 Copa America and 2022 World Cup winners face Colombia at Miami's Hard Rock Stadium.

He has endured a mixed tournament, needing four games – and 12 shots – to score his first goal as he finally got off the mark against Canada in the semi-finals.

A muscle injury forced Messi to sit out Argentina's third group-stage match against Peru, but he says he is fully fit and raring to go ahead of Sunday's showpiece game.

Speaking to Dsports, the eight-time Ballon d'Or winner said: "With Canada I felt very good physically. 

"Against Chile I had an adductor problem and I no longer played comfortably. I was already slowed down, it bothered me when I had to stand up or move laterally. 

"Versus Ecuador [in the last eight] I arrived just in time too. I was fine from the injury, but I had it in my head that I had something wrong. 

"In the last match I lost my fear, I felt better and for the final I will feel even better."

Many believe Messi could call time on his glittering international career after Sunday's final, after he said he was fighting his "last battles" with Argentina last week.

Messi is set to become the first player in Copa history to feature in five finals, having led his nation to glory three years ago after losing the 2007, 2015 and 2016 finals.

He currently shares the record for most final appearances with former team-mate Javier Mascherano, who played in the 2004, 2007, 2015 and 2016 showpiece matches.

Colombia boss Nestor Lorenzo has hit out at the decision to have an extended half-time break during Sunday's Copa America final to facilitate a performance by Shakira.

Colombia will go in search of their second Copa America title at the Hard Rock Stadium in Miami, while holders Argentina are targeting a record-breaking 16th triumph.

Tournament organisers are planning a 25-minute interval, rather than the traditional 15, with Colombian pop sensation Shakira performing during the break.

While Lorenzo says the extended break will not give an advantage to either team in particular, he is worried about the potential for it to impact players' conditioning.

Speaking at his pre-match press conference, Lorenzo told reporters: "I hope you enjoy, Shakira is great. 

"For a final, when the rules change for both teams, bad pitches for both or same weather for both, then I can't say if it's bad, or if it favours one side.

"I can't understand it, I wish it were like the rest of the games."

Lorenzo pointed to incidents which saw Argentina, Chile, Uruguay and Venezuela sanctioned by CONMEBOL for late arrivals after half-time during the group stage.

"When we came out in the 16th minute we were sanctioned, but now that there is a show we can come out in the 20th minute," he said.

"Players can get cold, but it's on both sides. I found out today that this is how it is, and that's it."

Nestor Lorenzo acknowledged Colombia must be "the best version" of themselves if they are to beat Argentina in Sunday's Copa America final.

Los Cafeteros are preparing for their first appearance in the tournament's showpiece since lifting the trophy on home soil in 2001.

Lorenzo's side topped Group D ahead of Brazil with seven points from nine, before inflicting a 5-0 rout on Panama in the quarter-finals.

Colombia then edged out Uruguay 1-0 in the semi-finals - despite playing over half the contest with 10 men following Daniel Munoz's dismissal - to stretch their unbeaten streak to a national record of 28 matches.

Lorenzo is delighted by the way his players have overcome the different challenges presented to them en route to the final, where Argentina await.

However, he knows they must produce a perfect display if they are to dethrone the reigning Copa America and world champions.

"We need to be the best Colombia, the best version, to beat Argentina, the champions of everything," Lorenzo told reporters during his pre-match press conference.

"To win against Argentina, we have to be very well-prepared, because they are the champions. It will be a very demanding match.

"Every day, overcoming an obstacle means you grow, and we have had several games with these types of situations that made us reinvent ourselves in the game and the team reacted.

"We are in a very good moment. I think the team still has room for improvement, and we hope to have a great performance tomorrow and take a step forward in that sense as well."

Lionel Scaloni hopes Angel Di Maria can retire from international duty "in the best possible way", but did not reveal whether he will start Argentina's Copa America final showdown with Colombia.

The veteran winger - and winner of 144 caps - is set to call time on his illustrious career with La Albiceleste at the conclusion of this tournament, where they are looking to successfully defend their crown.

Di Maria has played a crucial role in Argentina's success in recent years, scoring the winner against Brazil in the 2021 Copa America final, while netting in the 2022 World Cup final victory over France.

The 36-year-old has continued to demonstrate his importance for Scaloni's side in the United States, playing in four of their five games en route to their sixth Copa final in eight editions.

It is unclear if Di Maria will feature at the Hard Rock Stadium but, either way, his head coach wants to give him an ideal send-off.

"We hope that everything goes well, and that Angel can retire in the best possible way," Scaloni told reporters during his pre-match press conference.

"Even though we know it will be his last game, we will always decide first what is best for the team. If he has to play, it's because he has to play. If we decide not to play him, it's because we think differently.

"It is a final and every final has its nuances. We will try to play it and win it. Every team that goes to a final knows the flavour of it and what's at stake."

Standing in Argentina's way is Colombia, whose semi-final victory over Uruguay was marred by crowd violence.

CONMEBOL are currently investigating the incident which saw La Celeste players climbing into the stands at the Bank of America Stadium when family members were caught up in violence involving Los Cafetero supporters.

Scaloni empathised with Uruguay boss Marcelo Bielsa, who vehemently defended his players' actions, and is hopeful there will be no such occurrence during the final.

"We ask the players to set an example, but when something like this happens, no one acts differently," the Argentina coach said. "I hope it doesn't happen again. I don't know if it's anybody's fault, but to see your family in a riot or nearby must be desperate.

"I hope the fans have a party [at the final]. I want it with all my heart. Apart from the joy of winning the title, I think it would be a joy for everyone if it ends well."

Nestor Lorenzo acknowledged Colombia must be "the best version" of themselves if they are to beat Argentina in Sunday's Copa America final.

Los Cafeteros are gearing for their first appearance in the tournament's showpiece since lifting the trophy on home soil in 2001.

Lorenzo's side topped Group D ahead of Brazil with seven points from nine, before inflicting a 5-0 rout on Panama in the quarter-finals.

Colombia then edged out Uruguay 1-0 in the semi-finals - despite playing over half the contest with 10 men following Daniel Munoz's dismissal - to stretch their unbeaten streak to a national record of 28 matches.

Lorenzo is delighted by the way his players have overcome the different challenges presented to them en route to the final, where Argentina await.

However, he knows they must produce a perfect performance if they are to dethrone the reigning Copa America and world champions.

"We need to be the best Colombia, the best version, to beat Argentina, the champions of everything," Lorenzo told reporters during his pre-match press conference.

"To win against Argentina, we have to be very well-prepared, because they are the champions, it will be a very demanding match," he added.

"Every day, overcoming an obstacle means you grow, and we have had several games with these types of situations that made us reinvent ourselves in the game and the team reacted.

"We are in a very good moment. I think the team still has room for improvement, and we hope to have a great performance tomorrow and take a step forward in that sense as well."

Lionel Messi hopes team-mate Angel Di Maria can sign off with "another goal" when Argentina face Colombia in Sunday's Copa America final.

Di Maria announced in November that the tournament in the United States would mark the last time he represents his country, for whom he has earned 144 caps.

The 36-year-old has played a crucial role in La Albiceleste's success in recent years, scoring the winner against Brazil in the 2021 Copa America final, while netting in the 2022 World Cup final victory over France.

Di Maria, who also scored the only goal against Nigeria in the 2008 Olympic final, continues to demonstrate his importance for Lionel Scaloni's side, playing in four of their five games en route to their sixth Copa final in eight editions.

And Messi wants his fellow winger to make one more vital contribution before bringing the curtain down on his illustrious international career.

"Who knows? Maybe he'll score another goal in the final, like he did in all the previous ones he's played in. It would be extraordinary," the eight-time Ballon d'Or winner said in an interview with Direct TV Sports.

"We always tell him that if everything goes well, we have World Cup qualifiers coming up. Nevertheless, 'Fideo' [Di Maria] has made up his mind and there's nothing that can change it."

Should he appear in the final, Di Maria would join Javier Zanetti on 145 caps, behind only Messi (186) and Javier Mascherano (147) on Argentina's all-time list.

Meanwhile, his tally of 31 goals is only bettered for La Albiceleste by Messi (109), Gabriel Batistuta (56), Sergio Aguero (41), Hernan Crespo (45) and Diego Maradona (34), and he knows he can retire from international duty with his head held high.

"I'm not ready for my last game with the national team, but now it's time," an emotional Di Maria said.

"A thousand things could happen [in the final], but I think that whatever happens, I can leave through the big door. I've done everything to be able to leave through that door.

"I'll take a lot of trophies with me, but the people, team-mates and friends I'll take with me is something you can't buy with anything."

The stage is set for what could be Lionel Messi's international swansong, as Argentina face Colombia in Sunday's Copa America final in the forward's new home of Miami.

The Hard Rock Stadium is the venue as Messi and La Albiceleste go in search of a record-breaking 16th Copa America crown, currently level with Uruguay on 15. It would also be a second in a row after they overcame old rivals Brazil in the 2021 final.

Standing in their way, however, are arguably the most impressive team at the tournament in Colombia.

Unbeaten in 28 games – a new national record – and led by a rejuvenated James Rodriguez, who is surely the favourite for Player of the Tournament honours, Los Cafeteros downed a much-fancied Uruguay side with 10 men in the last four and are sure to present a stern test.

Ahead of the showpiece game, we dive into the best Opta data surrounding the two finalists. 

What's expected?

Argentina began the tournament as favourites, being given a 30.8% chance of securing back-to-back titles for the first time since 1993 by the Opta supercomputer.

The supercomputer is still on their side ahead of the final, giving them a 50.9% chance of winning the match in 90 minutes.

Colombia are assigned a 25.4% chance of victory and a 23.6% chance of taking the game to extra time (which will take place if required after being scrapped for all other knockout matches) and potentially penalties.  

Argentina have won their last two Copa America shoot-outs, against Ecuador in this year's quarter-finals and Colombia in 2021, though they have lost three of their last four finals at the competition on spot-kicks, versus Brazil in 2004 and Chile in both 2015 and 2016.

Overall, Lionel Scaloni's team are given a 63% chance of lifting the trophy to Colombia's 37%. 

Colombia will be featuring in just their third Copa America final (also 1975 and 2001), becoming the fourth team to reach multiple finals at the competition this century, after Argentina (six), Brazil (four) and Chile (two).

Argentina have now reached the final at six of their last eight major tournaments (World Cups and Copa America). The only exceptions were at the 2018 World Cup and the 2019 Copa, losing to the eventual champions (France and Brazil) in both instances.

Colombia have only won one of their last 12 meetings with Argentina (five draws, six defeats) – a 2-0 group-stage win at the 2019 Copa America. The teams' last draw led to Colombia losing on penalties in the 2021 Copa quarter-finals, with Davinson Sanchez, Yerry Mina and Edwin Cardona all unsuccessful from 12 yards.

The teams have met on 15 previous occasions in the Copa America, with Argentina recording seven wins to Colombia's three and the remaining five being drawn.

Fitting farewell for the GOAT?

Sunday's final could very well be the end of an era, with arguably the greatest footballer of all time contemplating international retirement after the match.

While there are plenty stateside who are desperate to see Messi continue his glittering Argentina career until the 2026 World Cup, the eight-time Ballon d'Or winner said this week he is fighting his "last battles" on the international stage.

Having led Argentina to glory at the 2021 Copa and the Qatar World Cup, Messi could go out on a high by inspiring his country to three straight major tournament successes, a feat they only previously achieved by winning three consecutive Copas in 1945, 1946 and 1947, with the World Cup not held during that time.

It took him a while, but Messi finally got up and running at this year's Copa with a goal in Tuesday's 2-0 semi-final victory over Canada, converting his 12th shot of the tournament.

He has now scored at six different editions of the Copa America, matching the record set by Zizinho all the way back in 1957. Messi has netted at the 2007, 2015, 2016, 2019, 2021 and 2024 editions, only failing to get on the scoresheet in 2011.

His semi-final strike came 17 years and one day after his first Copa America goal, versus Peru in 2007. That gap is the longest between goals for a single player in the tournament's history, breaking another record previously held by Zizinho (15 years and 52 days between 1942 and 1957).

Another trophy on Sunday would enable him to end what had previously been a disappointing Argentina career with a perfect run of three tournament triumphs.

There is also the small matter of another international trophy pulling him clear of his great rival Cristiano Ronaldo, who led Portugal to glory at Euro 2016 and in the 2018-19 UEFA Nations League but now looks unlikely to add to that collection. 

Cafeteros the Copa's best?

Argentina may have star quality unmatched by any of their South American rivals, but they were made to work for knockout successes against Ecuador and Canada. Many would argue they have not been the tournament's outstanding team.

That honour may go to Colombia, who topped Group D ahead of Brazil before dumping out Uruguay – considered second-favourites for the trophy by some – in the semi-finals.

Nestor Lorenzo's team did not even require a full complement to overcome La Celeste, standing firm after Daniel Munoz's first-half red card as Jefferson Lerma's earlier header proved decisive. 

Lerma's goal was Colombia's fifth to come via a header at this tournament, the most by a team at a single edition since Argentina netted six times via that route in 1991, when they lifted the trophy.

Colombia's aerial prowess has been another string to their bow at a tournament where they have been extremely efficient in attack, scoring a competition-high 12 goals from 8.49 expected goals (xG), a tally that puts them second to Argentina (11.1). Colombia rank just sixth for touches in the penalty area (104) but third for shots from inside the box (59).

Only conceding twice, Lorenzo's side have also been solid at the back – a recipe for tournament success. 

Per game, they have averaged a tournament-low 0.51 expected goals against (xGA), as well as 9.6 shots faced (the third-best figure) and 2.2 shots on target faced (second-best). 

That solid backline has given James and Luis Diaz the platform from which to make things happen, with the duo ranking third and fourth, respectively, for expected assists (xA) among all players at the competition. 

Miserly at the back and with two of the competition's most creative players in attack, Colombia will back themselves to spoil Messi's Miami party.

PLAYERS TO WATCH

Argentina – Angel Di Maria

Di Maria made his 27th Copa America appearance in the last four, becoming Argentina's second-most capped player in the competition, behind Messi (38 matches).

The former Real Madrid wideman will play his final international match on Sunday, and he could go out with a bang, having earned a reputation as a big-game player.

Di Maria, who has 31 goals in 144 games for La Albiceleste overall, scored the winner in the 2021 Copa America final versus Brazil and also got on the scoresheet in the 2022 World Cup showpiece game against France.

Only James (17), Nicolas de la Cruz (14) and Messi (13) have bettered his nine chances created at this tournament, while he also ranks sixth for xA (1.01) and only Messi has matched his tally of four chance-creating carries. 

Colombia – James Rodriguez

Colombia captain James has looked a player reborn at this tournament, recording six assists, with the most recent teeing up Lerma's semi-final winner versus Uruguay.

That meant he surpassed Messi (five in 2021) for the most assists at a single edition of the Copa America since this data began being recorded by Opta in 2011.

A remarkable 12 of his 17 chances created at this tournament have come from set-pieces, and with a cagey affair potentially in store, his dead-ball prowess could prove decisive.

Five of Colombia's 12 goals have come from corners or indirect free-kicks, with James' deliveries helping them surpass their previous best goalscoring return at a Copa America (11 in both 1975 and 2001).

Lionel Scaloni has not ruled out trying to "convince" Angel Di María to reverse his Argentina retirement decision after the 2024 Copa America.

The 36-year-old announced in November that the tournament in the United States would mark the last time he represents his country.

Di Maria earned his 144th cap for Argentina in Tuesday's 2-0 win over Canada as La Albiceleste reached a sixth Copa final in eight editions.

And having played in four of Argentina's five games en route to this latest final, starting three of those, Di Maria continues to show his importance to the world champions.

Ahead of what is scheduled to be Di Maria's final Argentina game on Sunday, against either Colombia or Uruguay, Scaloni told reporters: "You know how I feel about Angel.

"We don't want to retire him earlier than needed. We don't want to feel melancholy. We have to let him play, and then we'll see if we can convince him or not to stay with us.

"But so far, he's here, and he has to be allowed to enjoy this moment."

Nicolas Otamendi is also set to bow out of the international scene after next weekend's final, while uncertainty surrounds whether Lionel Messi will stay on.

All three played a part as Argentina saw off Canada at MetLife Stadium in New Jersey to remain on course for a third major title in three years.

Canada had the better of the early exchanges, but Julian Alvarez's 22nd-minute opener was added to by Messi from close range early in the second half.

"It is extremely tough to reach another final," Scaloni said. "It is tough because we know how hard it is to get there.

"The bar has been set very high. Everyone thought it was going to be a bed of roses and it wasn't like that at all. Canada proved it by being a very difficult opponent."

Jesse Marsch is "very proud" of what his Canada players achieved in the 2024 Copa America as their tournament ended with defeat to Argentina.

The competition debutants finished second to Argentina in Group A before defeating Venezuela on penalties in the quarter-finals.

After defying the odds to reach the last four, Canada's dream run was ended on Tuesday as they lost 2-0 to Argentina in New Jersey.

Canada will co-host the next World Cup along with the United States and Mexico, with that tournament now very much in Marsch's sight.

"What I said to the team afterwards is I know that they're very disappointed, but I'm very proud of them," Marsch told reporters. 

"We've put together some incredible performances and we're just starting our process. We need to find a way to expand our player pool. 

"We need to continue to challenge our group to come together and be able to perform in moments like this.

"But in general, we've had a wonderful five-six weeks together and it's gone way better than any of us could have scripted. 

"There's still a lot of work to do, but we've built a really good foundation."

Marsch only took over as Canada head coach two months ago but his style of play was already clear to see across the tournament.

Canada now have a third-place play-off against either Colombia or Uruguay to come on Saturday, with Marsch planning on making changes.

"I'm trying to really build and develop every single player in this pool so that we can have a real 26-man squad when it comes to 2026," he said.

"So the match on Saturday will also be vital for that because we'll make some changes. 

"We'll get some new faces on the pitch and challenge them to be able to see if they can hold up in these kinds of matches."

Canada started the better against Argentina at the MetLife Stadium and squandered chances prior to Julian Alvarez's 22nd-minute opener.

Lionel Messi added a second for the reigning world champions early in the second half, but Canada can still be pleased with their run.

"They're the best team in the world, but we had our chances in the beginning of the game," midfielder Stephen Eustaquio told TSN.

"If we scored one of our chances, the story of the game would probably have been different. 

"To get here, the last four of the Copa America, it's a big achievement."

Lionel Messi wants to continue enjoying his football with Argentina while he can after helping his nation reach another Copa America final.

The Inter Miami forward netted early in the second half of Tuesday's 2-0 win over Canada as Argentina reached a sixth final in eight editions.

Julian Alvarez had earlier given the reigning champions a first-half lead at MetLife Stadium in New Jersey against a valiant Canadian side.

Messi's international future remains unclear, while team-mate Angel di Maria will definitely call time on his Argentina career after this tournament.

Speaking to TyC Sports after setting up a final with either Uruguay or Colombia, Messi said: "Let's enjoy what we are experiencing as a group.

"I'm living it as I have been living everything lately - enjoying it and being aware, as it happens to Fideo (Di Maria) and Ota (Nicolas Otamendi), that these are the last battles.

"It is not easy to be in a final again, to compete again to be champions."

Argentina weathered an early storm against Canada before Alvarez's ninth international goal gave them the lead with 22 minutes played.

Messi then extended his side's lead six minutes into the second period when turning home Enzo Fernandez's goal-bound effort from close range.

La Albiceleste now have a third major title in three years in their sights, having won the Copa America in 2021 and the World Cup in 2022.

Whether Messi will still be part of the squad for the 2024 World Cup remains uncertain, but head coach Lionel Scaloni wants him part of the group in some capacity.

"We have to let him be and we will never be the ones to close the door," Scaloni said when asked about Messi's international future.

"He can be with our team for as long as he wants to be. And if he wants to retire but still come and hang around with us, it would be great."

Colombia and Uruguay meet in Wednesday's second semi-final at Bank of America Stadium in North Carolina.

Julian Alvarez and Lionel Messi secured Argentina's passage to the Copa America final following a 2-0 victory over Canada at the MetLife Stadium. 

The defending champions weathered an early storm and took the lead through Alvarez's ninth international goal in the 22nd minute. 

Messi put the game beyond Canada's grasp early in the second half, turning home Enzo Fernandez's goal-bound effort from close range. 

Argentina will face the winner of tomorrow's semi-final clash between Uruguay and Colombia in Miami this weekend. 

Canada started immediately on the front foot, startling their opponents early on as Jacob Shaffelburg was presented with two opportunities, but unable to test Emiliano Martinez on both occasions. 

Largely a passenger in the opening 10 minutes, Messi was given his first sight of goal but could not find the target with his effort from outside the area. 

Despite La Albiceleste's lacklustre opening, a moment of individual quality sparked the contest into life. 

Rodrigo De Paul was allowed time deep in midfield, picking out the run of Alvarez before taking a touch and prodding the ball beyond Maxime Crepeau for his second goal of the tournament - his first also came against Canada in their opening group game. 

Argentina's grip tightened on the contest and they almost doubled their lead when an uncharacteristic mistake by Alphonso Davies was almost punished by Angel Di Maria, with Messi going close again before the interval. 

Lionel Scaloni's side would increase their lead six minutes into the second half, with Messi netting his 109th international goal after turning home inside the area, which was eventually given following a VAR review for offside.

Alvarez almost doubled his tally following an exquisite pass from Di Maria, only to see his effort repelled by Crepeau with the goal at his mercy. 

Canada's efforts in pulling a goal back were dented when captain Davies was forced off with an injury with 20 minutes remaining, but continued to push for a way back into the contest. 

Tani Oluwaseyi came the closest for Jesse Marsch's side, heading narrowly wide of Martinez's goal as Argentina saw out the triumph as they edge close to a record-breaking 16th Copa America title. 

Alvarez the man of the moment for Argentina

Alvarez has made a name for being a big game player for Manchester City, and that form has seemingly transpired to international level for Lionel Scaloni's side. 

His ninth international goal saw him become the fourth player to score in both the Copa America and World Cup semi-finals, alongside Messi, Romario and Diego Forlan. 

With Messi expected to call time on his international career following the conclusion of the tournament, Alvarez 

But the Argentina captain continued to showcase his class on the international stage, with Canada the 38th different opponent Messi has scored against while playing for La Albiceleste - his 21st different opposition in competitive outings. 

Canada's fairytale Copa run comes to an end

Having already faced Argentina in the group stages of the competition, Marsch was under no illusion about the size of the task in front of him and can be proud of his side's efforts against the defending Copa America chances. 

But again, their wastefulness in front of goal proved costly and, against the best teams, it is something you are unable to get away with. 

Having managed nine shots during the game, Canada mustered just two on target. Five of those efforts also came from inside the area and failed to trouble Martinez. 

While their tournament may be over, Marsch has solid foundations to build on for the future with the 2026 World Cup now the goal for Canada. 

Despite injury concerns, Lionel Scaloni is adamant that Lionel Messi is fit to play in their Copa America semi-final against Canada.

The Argentina captain sustained a hamstring injury in their second group game against Chile, forcing him out of the following match against Peru.

However, Messi returned for their quarter-final meeting with Ecuador, notably missing the first spot-kick in the penalty shootout, which they won thanks to two Emiliano Martinez saves.

After Messi admitted he "trained with fear" ahead of his return from injury against La Tricolor, Scaloni has brushed off any worries about his star man's fitness.

"99% of the time, [Messi] is fit to play," Scaloni said. "It's never happened to me that he's not fit to play.

"Every time he's come out on the pitch, he's fit to play. For [Canada], he's fit to play, without a doubt.

"It's a very easy decision for me, because it's a very frank decision, that if he's fine, he plays; and if he's not fine, he plays the last 30 minutes. It's that easy.

"It's true that that won't ever weigh on me. I know what he can give us even if he's not in optimal condition. I wouldn't make the grave mistake of not putting him on the pitch knowing that he gives us a lot, so that's indisputable."

Argentina opened their Copa America title defence with a 2-0 victory over Canada on June 20.

Scaloni acknowledged the benefit of that first meeting, though conceded Jesse Marsch was unlikely to take the same approach in a bid to reach the final.

"Canada has players who are physically strong and also technically good, with a coach who has conveyed an aggressive way of playing," he added.

"They have made things difficult for all teams. Physically, it's difficult to match them, but with our assets, we hope to play the game on our side.

"All coaches take notes to correct mistakes and hurt our opponents. Each coach will have to do something different. We will try to have the ball and stop them from playing their game."

Canada must produce the performance of their lives to have any chance of upsetting holders Argentina to reach the Copa America final, acknowledges Jesse Marsch.

Marsch's team will face the World Cup winners for a final berth at the MetLife Stadium on Tuesday, having overcome Venezuela in a penalty shoot-out in the last eight.

They are just the fourth CONCACAF team to reach the Copa semi-finals and the third to do so on their debut, after Mexico (1993 runners-up), Honduras (third in 2001) and the United States (third in 1995).

They face the sternest of tests next up, however, having already lost to Lionel Messi and the rest of Argentina's stars in their opening group-stage game.

Julian Alvarez and Lautaro Martinez were on target in that match as Lionel Scaloni's team triumphed 2-0 in Atlanta, rifling off 19 shots worth 3.02 expected goals (xG) to Canada's 10 (1.16 xG).

While Canada have won plenty of admirers on their run to the last four, Marsch knows they need to step up further on Tuesday.

"Argentina will have to be the best match we've ever played and it still might not be enough," he said. "But whatever. We're going to go for it."

Captain Alphonso Davies echoed those sentiments but pointed out Canada had given Argentina a scare in their earlier game, saying: "It's going to take everything. We played them in the group stage and we played well but didn't get the win we wanted."

Argentina boss Scaloni hit out at the quality of the pitch after that earlier meeting at Mercedes-Benz Stadium, and Messi says the surfaces have had an impact throughout the tournament.

"The pitch always has an influence. It's a reality that the pitches aren't good," he told reporters, as quoted by The Athletic.

"I think the best one was the one in Miami, which was good from what you saw from the outside at least. It's natural and that's already different. Of course, it has an influence."

PLAYERS TO WATCH

Argentina – Alexis Mac Allister 

Mac Allister assisted Lisandro Martinez's opener versus Ecuador in the last eight, then held his nerve from the spot as the world champions triumphed in a shoot-out after a 1-1 draw.

The Liverpool midfielder has two assists at this year's tournament. Since such data began in 2011, only Lionel Messi (in 2011, 2015, 2016 and 2021) has ever provided three or more assists for Argentina at a single edition of the Copa America. 

Mac Allister has completed 122 of his 135 passes at this tournament, with 70 of those being played in the opposition half. With Canada likely to sit deep, it could fall on him to keep things ticking over and provide service for Messi and his fellow attackers.

Canada – Maxime Crepeau

Crepeau was forced into six saves in Canada's Copa America opener versus Argentina, and he could be busy again here.

However, he has been in excellent form throughout this tournament, conceding three goals from 4.95 expected goals on target (xGoT) faced, with only Claudio Bravo (3.66 goals prevented) and Rafael Romo (2.36) overperforming their underlying goalkeeping statistics by a greater margin.

Only Sergio Rochet and Emiliano Martinez (three each) have bettered his two clean sheets at this tournament. He will have his work cut out to keep another, though.

MATCH PREDICTION: ARGENTINA WIN

Argentina have now reached the semi-finals at seven of their last eight major tournaments, with the 2018 World Cup being the only exception.

They have won their last 10 matches against CONCACAF opponents in official competitions, not conceding a goal in any of their last six such games.

Additionally, the defending champions have reached the last four at five of the last seven editions of the Copa America, and only two of them – Colombia in 2004 and Chile in 2019 – failed to make the final. The omens, then, are not good for Canada.

It will be the fifth time Argentina have faced the same opponents twice at a single edition of the Copa America since the current format was introduced in 1993. Two of the previous four instances included a semi-final meeting (Colombia in 1993 and Paraguay in 2015), with the other two including the final (Mexico in 1993 and Chile in 2016).

La Albiceleste did, however, only win one of those four editions, lifting the trophy in 1993, then waiting 28 years to reclaim their place as South America's finest in 2021.

They are assigned an 84% chance of reaching the final by the Opta supercomputer, with Canada out to cause one of the greatest upsets in the history of the competition.

OPTA WIN PROBABILITY

Argentina – 76.7%

Canada – 9.8%

Draw – 13.6%

Lionel Messi was fearful ahead of his return to action for Argentina at the Copa America.

Messi sat out Argentina's win over Peru in the group stage, but despite Lionel Scaloni saying the eight-time Ballon d'Or winner was a doubt to feature against Ecuador in the quarters, he started on Thursday.

The 37-year-old had just 32 touches in a 1-1 draw, marking his fewest touches in a competitive match for his country in which he has played 90 minutes since 2011.

Messi subsequently missed his penalty in the shootout, but goalkeeper Emiliano Martinez spared his blushes in a 4-2 victory for the defending Copa America champions.

When asked how he had been feeling ahead of the tie, Messi told reporters (via The Athletic): "The truth is bad.

"With a lot of uncertainty, with lots of fear when I was training, a lot of desire to be here and doing everything possible to be able to play.

"I was able to be here and [help] the team."

Messi explained it was no surprise to Argentina that they faced such a stern challenge from Ecuador.

"The truth is it was a difficult match, which was very hard to play," Messi added.

"We knew it was going to be that way because they’re a great team, a hard team who press well, who have intense, dynamic players, and when they have the ball they do damage as well.

"We expected this kind of game."

Argentina have now extended their unbeaten streak against Ecuador to 17 matches at the Copa America (W11 D6). This is the third longest unbeaten run for La Albiceleste against a single opponent in the competition, following a 30-match run against Chile (W22 D8, excluding penalty shootouts) and 26 against Paraguay (W20 D6).

Messi and Co. will face either Canada or Venezuela in the last four.
