Lionel Messi marked his return from short-lived international retirement with the only goal as Argentina defeated Uruguay 1-0 to score a crucial 2018 World Cup qualifying victory on Thursday.

Messi, who had dramatically announced the end of his international career in June following Argentina's Copa America Centenario final defeat to Chile, scored via a deflected shot in the 42nd minute to spark wild celebrations in Mendoza's Estadio Malvinas.

The victory -- the first under the reign of new coach Edgardo Bauza -- catapulted Argentina into first place in South America's marathon round-robin qualifying campaign with 14 points after seven games.
