Argentina's 2-0 victory over Algeria in the 2026 World Cup is a testament to the enduring brilliance of Lionel Messi, who scored twice to become the oldest player to ever score more than once in a World Cup game. But this match was more than just a showcase for Messi's genius; it was a microcosm of the challenges facing Argentina as they defend their title. The team's heavy reliance on Messi's moments of brilliance, 20 years after his World Cup debut, raises deeper questions about their long-term prospects. While Messi's record-breaking goal against Serbia in 2006 marked the beginning of a remarkable journey, it also underscores the fragility of their success. The team's lack of clarity in attack and susceptibility to quick attacking sequences from opponents are concerns that cannot be ignored. As Argentina look to build on their World Cup title, they must find a way to distribute the load and reduce their dependence on Messi. The team's two right-backs, Molina and Montiel, are incredibly interchangeable, and their lack of impact suggests that they may need to consider other options. The substitution of Lautaro Martinez for Julian Alvarez and Nicolas Gonzalez for Thiago Almada offered a glimmer of hope, but it remains to be seen if these changes will be enough to address the team's underlying issues. The match also highlighted the importance of set-piece strategy. Argentina's failure to capitalize on their corner kicks and free kicks demonstrated the need for a more nuanced approach to these situations. As the team looks to the future, they must also consider the impact of the pitch on the game. The strange behavior of the ball, which caused it to run erratically in places, suggests that the surface may have played a role in the outcome of the match. In conclusion, Argentina's victory over Algeria was a reminder of the enduring brilliance of Lionel Messi, but it also raised important questions about the team's long-term prospects. As they look to defend their World Cup title, they must find a way to reduce their dependence on Messi and address the underlying issues that have plagued them in recent years. The team's future depends on their ability to adapt and evolve, and it remains to be seen if they have what it takes to rise to the challenge.
