KANSAS CITY, Mo. - Lionel Messi launched what many view as his farewell World Cup campaign with a record-setting performance on Tuesday in the tournament opener.

Arrowhead Stadium echoed with chants of his name as the captain became the first footballer to appear in six FIFA World Cups. He played 80 minutes and netted a hat trick during Argentina's 3-0 victory against Algeria, etching his name deeper into tournament lore. The Albiceleste skipper also matched Miroslav Klose's mark of 16 World Cup goals and equaled the German's 17 victories in the competition.

Yet Messi brushed aside the statistical milestones.

"It is special to stand alongside Klose and Ronaldo in those lists, but those figures hold little value to me," Messi remarked following the match.

Supporters had anticipated this return for nearly four years. After claiming the trophy in Qatar at age 35, the now 38-year-old aims to retain the crown. He debuted in 2006 as a promising youngster and now carries the weight of defending champions.

"He has faced various situations yet remains available," coach Lionel Scaloni noted. "His influence has always been immense, and it grows even greater now."

Doubts surrounded his availability before the tournament. Messi avoided firm commitments, stressing physical condition as the key factor in any decision.

"I focus on feeling well and staying true to myself," he stated in September 2025. "If I am not at my best, I would rather step aside. No choice has been finalized yet."

Minor issues arose during preparations, most notably a hamstring concern in late May that sidelined him briefly from Inter Miami duty and caused him to miss one pre-tournament friendly.

Those worries faded once play began against Algeria. Messi dictated the tempo from the outset, seeing an early effort disallowed before opening the scoring with a trademark left-foot finish after 17 minutes.

Two additional strikes followed after the interval, completing his treble. Beyond goals, he registered four shots on target, completed 37 passes and covered 247.4 meters with the ball at his feet.

His withdrawal in the 80th minute prompted a lengthy ovation, with fans chanting his name and offering bows of respect. Even opposing supporters joined the applause.

"Words fall short when describing him," teammate Alexis Mac Allister said. "Anyone doubting his importance saw the truth tonight. We build everything around him."

Scaloni added: "He has delivered at this level for two decades. Supporters worldwide want to watch him play. We must savor every moment he offers."

The expanded 48-team format offers added security for top sides, placing Argentina favorably ahead of their next group fixture versus Austria. Early signs suggest the squad is primed to protect its crown.

"Victory brings belief for the challenges ahead," Scaloni concluded.

History shows only Italy and Brazil have retained the trophy, yet Messi has signaled clear intent to chase that rare achievement one final time.
