Aguero is on the sidelines after breaking a rib in a vehicle crash in Amsterdam at the end of September, an injury which kept him out of Argentina's final two World Cup qualifiers and was expected to prevent him from playing throughout the rest of October.
City star Sergio Aguero says he'd love to see his Argentina team-mate at the Etihad stadium.
The 29-year-old Barcelona forward would come at a large cost - his buy-out clause is £268.7m - but Aguero thinks if Messi was keen to make the move, finances would not be an issue.
"He said, "I don't believe so".
"The money isn't a problem here", Aguero told TyC Sport .
"I would love to [see Messi join] - who wouldn't love to have Leo in his team? - but he's a symbol of his club and I think it would be rather hard".
Because of the injury, the Argentina worldwide was unable to feature in his nation's crucial 2018 FIFA World Cup qualifiers against Peru and Ecuador.
Manchester City striker Sergio Aguero refuses to rule out the possibility of returning in time for Saturday's Premier League match against Stoke City. "I thanked him for what he is doing for the World Cup".
"I still do not know if I am going to play on Saturday". Today I trained normally, but without the group. I want to be certain and not have pain.
During the interview, Aguero was also asked about the possibility of being joined at City by countryman Lionel Messi.
