National coach Edgardo Bauza met with Messi in Barcelona this week hoping to convince him to rejoin the squad.
Bauza was due to announce his list of players for games against Uruguay on September 1 and Venezuela on September 6. A news conference was scheduled for the announcement at 21:00 GMT Friday.
"I sense that Messi wants" to rejoin the squad, Bauza told reporters on arriving back in Buenos Aires on Friday.
"I have no doubt that he wants to rejoin the national team ... I will talk to him today and finish my list." Bauza took over the job from Gerardo Martino and was tasked with turning things around ahead of the 2018 World Cup, amid a management crisis at the Argentine Football Association.
"There are a lot of issues that need to be resolved in Argentine football, but I prefer to help from within and not to criticise from the outside," Messi's statement said.
"I send my thanks to all of those who want me to continue playing for Argentina. I hope that we'll be able to give them something to cheer about soon."
