Argentina opens its FIFA World Cup title defense in Group J, chasing history as it bids to become the first nation in 64 years to retain the trophy. Coach Lionel Scaloni's side is joined by Algeria, back after a 12-year absence; Austria, returning to the finals for the first time since 1998; and first-time participants Jordan.

Argentina: Built to Defend the Crown

The reigning world and continental champions arrive in commanding form. Scaloni's side swept through South American qualifying, finishing nine points clear of second-placed Ecuador with 12 wins from 18 matches. The 48-year-old coach has refined a mature 4-3-3 system since taking charge in 2018, and 17 members of the Qatar 2022 squad remain, providing invaluable tournament experience.

The team's spine is formidable: Emiliano Martinez commands the goal, Cristian Romero and Lisandro Martinez anchor a Premier League-tested central defence, and Enzo Fernandez orchestrates a midfield that balances work rate with creativity. Up front, Lautaro Martinez and Julian Alvarez offer contrasting attacking profiles, supported by Rodrigo De Paul, Alexis Mac Allister, and Giovani Lo Celso. Argentina faces Algeria in Kansas City and plays both Austria and Jordan in Dallas — a schedule that poses few obvious obstacles for the runaway group favourite.

Star player — Lionel Messi: Competing at a record-equalling sixth World Cup at the age of 38, the Argentina captain holds national records for appearances (198) and goals (116). His 13 World Cup goals make him his country's all-time leading scorer at the tournament. The one honour still missing from a collection that includes World Cup Golden Balls in 2014 and 2022 is the tournament's Golden Boot.

Player to watch — Nico Paz: The 21-year-old midfielder delivered one of Europe's standout individual seasons, scoring 13 goals and registering 8 assists in 40 appearances for Como, helping the club qualify for the UEFA Champions League for the first time in its history. A left knee issue interrupted his pre-tournament preparation, but medical staff are reportedly confident he will be fit for the opener against Algeria.

Algeria: Returning with Ambition and a Goalkeeping Question

Algeria is back at the World Cup for the first time since its celebrated run to the round of 16 at Brazil 2014, where the team pushed eventual champions Germany to extra time. Under Bosnian coach Vladimir Petkovic, appointed in early 2024, Algeria qualified with authority, winning 8 of 10 African preliminary matches and losing just once.

Attacking variety is Algeria's chief strength: captain Riyad Mahrez provides guile and set-piece quality, Mohamed Amoura — who scored 10 goals in qualifying — offers direct running, and teenage prospect Ibrahim Maza contributes unpredictability. The squad's most significant vulnerability lies in goal, where the three selected keepers share just 10 caps between them, and Algeria has kept only one clean sheet in its last 13 World Cup matches.

Star player — Riyad Mahrez: The 35-year-old Al-Ahli winger and Algeria captain has declared this his final World Cup. A Champions League winner and five-time Premier League champion with Manchester City and Leicester City, Mahrez is his country's second-highest all-time scorer with 38 goals in 114 caps. His touch, vision, and delivery from set pieces remain Algeria's primary creative weapons.

Player to watch — Ibrahim Maza: Already nicknamed 'Mazadona' by supporters for his close control, the 20-year-old Berlin-born playmaker featured in 28 Bundesliga matches for Bayer Leverkusen this season, contributing 3 goals and 4 assists while also gaining Champions League experience. Having represented Germany at youth level, Maza pledged his international future to Algeria and is the team's most exciting attacking prospect.

Austria: Rangnick's Pressing Machine Eyes Second Place

Austria returns to the World Cup stage after a 28-year absence, having topped UEFA qualifying Group H ahead of Bosnia and Herzegovina. Under German coach Ralf Rangnick, in charge since April 2022, Austria has developed into one of Europe's most recognisable high-pressing sides.

Attacking depth remains a concern: veteran striker Marko Arnautovic, now 37, remains central despite being in the twilight of his career, and the late injury ruling out Christoph Baumgartner further reduces Austria's goal threat. Nevertheless, the collective cohesion and tactical clarity of Rangnick's system make Austria the clear second favourite to advance from Group J.

Star player — David Alaba: Austria's captain and most decorated footballer, the 33-year-old has won nine major trophies in Spain alone at Real Madrid, including two Champions League titles, in addition to his decorated spell at Bayern Munich. Alaba had been a doubt following a muscle injury sustained in a warm-up friendly against Tunisia, but has been declared fit to travel.

Player to watch — Carney Chukwuemeka: The 22-year-old Borussia Dortmund midfielder switched his international allegiance from England to Austria in March, with FIFA ratifying the change in time for the tournament. Born in Vienna, Chukwuemeka was the top scorer for England's U-19 European Championship-winning side in 2022. Powerful, direct, and capable of breaking lines with his dribbling, he adds a different profile to Rangnick's midfield options.

Jordan: Debutants Targeting a Giant-Killing

Jordan arrives at its first-ever World Cup after nine failed qualifying campaigns, riding momentum from a historic run to the AFC Asian Cup final in 2024. Moroccan coach Jamal Sellami, who took charge in June 2024, has preserved the defensive organisation of his predecessor while introducing greater tactical flexibility.

The squad will be without striker Yazan Al Naimat, ruled out with a knee injury, though captain Ehsan Haddad has recovered from a lengthy layoff to lead the side. Jordan's compact defensive shape and reliance on quick transitions make them capable of frustrating stronger opponents, but the team can struggle when forced to chase a game. The realistic objective is to compete for one of the best third-placed spots — and, perhaps, spring a surprise.

Star player — Mousa Al-Tamari: Jordan's most dangerous attacker, the Rennes winger contributed 6 goals and 6 assists in 33 Ligue 1 appearances this season, ranking among the league's leading assist providers. Quick and comfortable cutting inside onto his left foot, Al-Tamari carries the responsibility of converting Jordan's limited counterattacking opportunities into goals.

Player to watch — Nizar Al Rashdan: The 27-year-old Qatar SC midfielder serves as Jordan's defensive anchor, tasked with winning the ball, disrupting opposition rhythm, and maintaining structural balance. With 39 international caps, he is among the more experienced figures in a squad navigating entirely new territory.

Group J Outlook

Argentina are overwhelming favourites to top the group, with Austria widely expected to secure second place. Algeria's attacking quality — and Mahrez's experience — gives them a realistic shot at the knockout rounds, while Jordan's debut campaign will be defined by whether their defensive discipline can earn a result that echoes through the tournament's history. All eyes, inevitably, will be on whether Messi can add a Golden Boot to a collection that already has almost everything else.
