The 2006 Argentina away shirt is forever linked with the emergence of Lionel Messi on the world stage, with the number 19 marking his role as a teenage prodigy at the 2006 FIFA World Cup. Worn during his debut tournament at just 18, the dark blue adidas design became iconic after Messi came off the bench against Serbia and Montenegro, registering both a goal and an assist in a historic 6–0 win—an early glimpse of the legend he would become.
