There will be no Lionel Messi for Argentina and no Neymar for Brazil in two decisive rounds of South American World Cup qualifying. Ahead of games against tough rivals, coaches Lionel Scaloni and Dorival Júnior are still wondering who will replace their stars.

Inter Miami forward Lionel Messi has been left out of Argentina's squad for their next two World Cup qualifiers.The 37-year-old returned to Miami's starting line-up for their Major League Soccer win over Atlanta United but reportedly picked up an injury during Sunday's game.

Martínez had been dealing with a muscle problem, missing Inter's Champions League match against Feyenoord. Despite scoring against Atalanta, further assessment confirmed the hamstring injury. His absence will require the coach to implement significant changes to the team’s strategy.
