Paulo Dybala and Angel Di Maria were included in coach Lionel Scaloni's 26-man Argentina World Cup squad on Friday after recovering from injuries but there was no place for Giovani Lo Celso.
Captain Lionel Messi will lead the squad in Qatar at his fifth and probably last World Cup.
Last month, Roma forward Dybala injured his thigh and Juventus winger Di Maria pulled his hamstring, seemingly putting their World Cup participation in doubt.
But Scaloni has decided to bring both despite neither playing in almost a month.
However, Villarreal midfielder Lo Celso, on loan from Tottenham, misses out as he needs surgery on his hamstring injury.
"They are all proud to be picked and to wear this jersey," said Scaloni of those selected.
Argentina are on a formidable run of 35 matches unbeaten and won the Copa America last year, defeating hosts Brazil 1-0 in the final at the Maracana in Rio de Janeiro.
They have not won the World Cup since the late Diego Maradona inspired them to victory in 1986, although they lost two finals to Germany in 1990 (then West Germany) and 2014.
"We are in a good moment with Argentina, the people are expectant, they are restless, they think we've already brought home the cup but it's not so easy," said Messi, 35, recently.
Two-time champions Argentina begin their World Cup campaign in Group C against Saudi Arabia on November 22 before further clashes with Mexico and Poland.
