Christian Pulisic has declared himself ready for World Cup duty with the U.S. men's national team after sitting out Friday's 2-0 win over Australia with a short-term calf issue. "I've been working every single day," the attacker said, signaling his availability for the tournament.

Pulisic trained all week with his teammates, suggesting the injury scare was minor. The 27-year-old is the USMNT's most dynamic attacking threat and a focal point of their World Cup ambitions.

His return provides a major boost to a U.S. side that has struggled for goals in recent friendlies. With Pulisic back, the team's rotation options improve ahead of their opening Group J match against Argentina.

Argentina, led by Lionel Messi, await in a high-stakes opener. The USMNT will need Pulisic at his sharpest to compete with the defending champions in a group that also includes Austria and a to-be-determined qualifier.

Messi, meanwhile, set the all-time World Cup goalscoring record on June 22 while wearing custom Adidas F50 El Ultimo Tango cleats — a retro design that has since sold out and now resells for over $800.
