Valentín Barco moved a step closer to Argentina’s World Cup conversation after being praised for the looseness and boldness he showed against Islandia. The left side of the team is open because Nicolás Tagliafico is injured, and that has pushed Barco into a discussion that is no longer about promise alone.
That matters now because Argentina is only four days from its debut, when every choice around the final squad starts to narrow. Barco was also named among the best players in the double friendly period before the World Cup, and Lionel Scaloni has already used him on the left, on the right and at times as an attacking midfielder, which keeps his profile broad at exactly the right moment.
The case for him is not just about a good match. He was described as playing excellent against Islandia, and the character of Colo Barco was presented as exactly the kind needed in the Argentina squad. For a young player, that is more than praise for one night; it is a sign that his personality and his football are being measured together, the way national-team decisions usually are.
Still, there is a catch in the argument. If the question is only who should fill the left-back spot on this day, the preference goes the other way and Lisandro Martínez comes first. That choice makes practical sense because Martínez has played as a fullback for Manchester United and, in his time at Ajax, replaced Nicolás Tagliafico many times. Barco is not pushed out of the picture by that view, but the role he is best suited for may be in midfield rather than fixed at left-back.
That is where the conversation settles for now: not whether Valentín Barco belongs in the picture, but how Argentina should use him when the debut arrives. The next test is no longer whether he can impress; it is whether Scaloni sees him as a left-back option, a midfield option or both.
