Argentina national football team in the context of "Copa América"

The FIFA World Cup, often called the World Cup, is an international association football competition among the senior men's national teams of the members of the Fédération Internationale de Football Association (FIFA), the sport's global governing body. The tournament has been held every four years since the inaugural tournament in 1930, with the exception of 1942 and 1946 due to the Second World War. The reigning champions are Argentina, who won their third title at the 2022 World Cup by defeating France.

The contest starts with the qualification phase, which takes place over the preceding three years to determine which teams qualify for the tournament phase. In the tournament phase, 32 teams compete for the title at venues within the host nation(s) over the course of about a month. The host nation(s) automatically qualify for the group stage of the tournament. The competition is scheduled to expand to 48 teams, starting with the 2026 World Cup.

Lionel Andrés "Leo" Messi (Spanish: [ljoˈnel anˈdɾes ˈmesi] ; born 24 June 1987) is an Argentine professional footballer who plays as a forward for and captains both Major League Soccer club Inter Miami and the Argentina national team. Widely regarded as one of the greatest players in history, Messi has set numerous records for individual accolades won throughout his professional footballing career, including eight Ballon d'Ors, six European Golden Shoes, and eight times being named the world's best player by FIFA. In 2025, he was named the All Time Men's World Best Player by the IFFHS. He is the most decorated player in the history of professional football having won 45 team trophies. Messi's records include most goals in a calendar year (91), most goals for a single club (672 for Barcelona), most goals in La Liga (474), most assists in international football (61), most goal contributions in the FIFA World Cup (21), and most goal contributions in the Copa América (32). A prolific goalscorer and creative playmaker, Messi has scored over 890 senior career goals and provided over 400 assists for club and country—the most of any player—resulting in over 1,300 goal contributions, the highest total in the sport's history.

Messi made his competitive debut for Barcelona at age 17 in October 2004. He gradually established himself as an integral player for the club, and during his first uninterrupted season at age 22 in 2008–09 he helped Barcelona achieve the first treble in Spanish football. This resulted in Messi winning the first of four consecutive Ballon d'Ors, and by the 2011–12 season he set the European record for most goals in a season and established himself as Barcelona's all-time top scorer. During the 2014–15 campaign, where he became the all-time top scorer in La Liga, he led Barcelona to a historic second treble, leading to a fifth Ballon d'Or in 2015. He assumed Barcelona's captaincy in 2018 and won a record sixth Ballon d'Or in 2019. At Barcelona, Messi won a club-record 34 trophies, including ten La Liga titles and four Champions Leagues, among others. Financial difficulties at Barcelona led to Messi signing with French club Paris Saint-Germain in August 2021, where he won the Ligue 1 title during both of his seasons there. He joined MLS club Inter Miami in July 2023.

The Iceland national football team (Icelandic: Íslenska karlalandsliðið í knattspyrnu) represents Iceland in men's international football. The team is controlled by the Football Association of Iceland, and have been a FIFA member since 1947 and a UEFA member since 1957. The team's nickname is Strákarnir okkar, which means Our Boys in Icelandic.

The team enjoyed success in the second half of the 2010s. In the qualifying rounds for the 2014 FIFA World Cup, Iceland reached the playoffs before losing to Croatia. Iceland reached its first major tournament, UEFA Euro 2016, after a qualification campaign which included home and away wins over the Netherlands. After reaching the knockout stages of Euro 2016, Iceland defeated England in the round of 16, advancing to the quarter-finals, where they lost to host nation France 5–2. The team qualified for the 2018 tournament on 9 October 2017, becoming the smallest nation by population to clinch a FIFA World Cup spot. They drew with Argentina in their opening match, but went out in the group stage.

The 2018 FIFA World Cup final was the final match of the 2018 World Cup, the 21st edition of FIFA's competition for national football teams. The match was played at the Luzhniki Stadium in Moscow, Russia, on 15 July 2018, and was contested by France and Croatia. The tournament comprised hosts Russia and 31 other teams who emerged from the qualification phase, organised by the six FIFA confederations. The 32 teams competed in a group stage, from which 16 teams qualified for the knockout stage. En route to the final, France finished first in Group C, with two wins and a draw, after which they defeated Argentina in the round of 16, Uruguay in the quarter-final and Belgium in the semi-final. Croatia finished first in Group D with three wins, before defeating Denmark in the round of 16 and Russia in the quarter-final – both through a penalty shoot-out – and then England in the semi-final. The final took place in front of 78,011 supporters, with more than 1.1 billion watching on television, and was refereed by Néstor Pitana from Argentina.

France took the lead through a controversial free kick that led to an own goal by Mario Mandžukić in the 18th minute – the first own goal in a World Cup final – before Ivan Perišić equalised 10 minutes later with a low shot into the corner of the goal. Shortly afterwards, France were awarded a penalty when Pitana ruled that Perišić had deliberately handled the ball. The decision resulted from a consultation with the video assistant referee, which was in use for the first time in a World Cup at the 2018 tournament. The decision was criticised by some pundits such as Alan Shearer, who labelled it "ridiculous", while others such as Chris Waddle thought it was correct. Antoine Griezmann scored to give France a 2–1 half-time lead. They extended that lead in the 59th minute, when Paul Pogba scored at the second attempt after Croatia defender Dejan Lovren had blocked his initial shot. Kylian Mbappé scored from outside the penalty area to make it 4–1, becoming the second teenager to score in a World Cup final (after Pelé in 1958). In the 69th minute, Mandžukić capitalized on a Hugo Lloris error to score a second for Croatia. The final score was 4–2 to France.

The Messi–Ronaldo rivalry, or Ronaldo–Messi rivalry, is a sporting rivalry in football propelled by the media and fans that involves Argentine footballer Lionel Messi and Portuguese footballer Cristiano Ronaldo, mainly for being contemporaries and due to their similar records and sporting successes. They spent nine seasons in the prime of their careers facing off regularly while playing for rival clubs Barcelona and Real Madrid.

Together, they have achieved various historical milestones, coming to be considered as two of the best footballers of all time. They are two of the most decorated players ever, having won 82 official trophies in total (Messi 48, Ronaldo 34) during their senior careers thus far, and have regularly broken the 50-goal barrier in a single season. According to IFFHS, they are the only two players to score over 800 goals each in their careers for club and country. Ronaldo holds the record for most official goals in a career.

Lionel Messi is an Argentine professional footballer who plays as a forward for and captains both Major League Soccer club Inter Miami and the Argentina national team. His individual achievements include eight Ballon d'Or awards, the most for any footballer. Having won 46 team trophies, he is the most decorated player in the history of professional football. Messi is often hailed as a genius, with his prolific goalscoring ability and high level dribbling, passing and playmaking earning him recognition as one of the greatest and most iconic players in football history. In 2024, US-based sports company ESPN named Messi the greatest player of the 21st-century.

Messi's club career began with Barcelona, where he rose through the youth ranks, making his first-team debut in 2004. Over the next years, Messi became the club's all-time top scorer, amassing numerous domestic and international accolades. During his tenure, Barcelona secured ten La Liga titles, seven Copa del Reys, four UEFA Champions Leagues, seven Supercopa de Españas, three UEFA Super Cups, and three FIFA Club World Cups. In August 2021, due to financial constraints faced by Barcelona, Messi signed for Paris Saint-Germain (PSG). Joining forces with fellow superstars Neymar and Kylian Mbappé, he won two Ligue 1 titles and one Trophée des Champions. In July 2023, Messi joined Inter Miami, leading the team to win their first-ever trophies with the Leagues Cup and the Supporters' Shield.

In association football, a kit (also referred to as a strip or uniform) is the standard equipment and attire worn by players. The sport's rules specify the minimum kit which a player must use, and also prohibit the use of anything that is dangerous to either the player or another participant. Individual competitions may stipulate further restrictions, such as regulating the size of logos displayed on shirts and stating that, in the event of a match between teams with identical or similar colours, one team (usually the away team) must change to different coloured attire, to avoid clashes.

Footballers generally wear identifying numbers on the backs of their shirts. Originally a team of players wore numbers from 1 to 11, corresponding roughly to their playing positions, but at the professional level this has generally been superseded by squad numbering, whereby each player in a squad is allocated a fixed number for the duration of a season. Professional clubs also usually display players' surnames or nicknames on their shirts, above (or, infrequently, below) their squad numbers.
