Despite losing to Chile on penalties in the final of Copa America, Argentina moved to the top of the Fifa rankings on Thursday for the first time in seven years.
Argentina lost in Santiago on Saturday but Gerardo Martino's side rose two places to top the rankings a year after losing to Germany in the 2014 World Cup final. Chile's victory moved them up eight spots to 11th.
Argentina's rise to the top means Germany and Belgium each drop a place to second and third respectively.
Following a string of solid results, Wales have risen 12 places to their highest ever world ranking of 10th, earning them a Pot 1 seeding in Uefa's 2018 World Cup qualifiers draw.
A 1-0 win over Belgium in Euro 2016 qualifying last month moved Chris Coleman's side to the top of Group B on 14 points from six matches. England moved six places up to ninth, one place behind Romania, which rose four places.
France fell 13 places to number 22.
