Manchester City boss Roberto Mancini says it is "ridiculous" that injured striker Sergio Aguero has been called up for international duty.
City expects the striker to be out until mid-September after suffering a knee injury in last week's opening Barclays Premier League win over Southampton.
But that has not stopped Argentina coach Alejandro Sabella from naming the 24-year-old to his squad for World Cup qualifiers against Paraguay and Peru on Sept. 7 and 11, respectively.
City had earmarked the Sept. 15 trip to Stoke as the earliest possible date for a comeback.
"It is impossible because Sergio needs a minimum of two weeks without training. After two weeks, he can start again," Mancini said. "If in one week if he could be ready to play it is different, but I think he needs another two weeks."
Mancini said Argentina has a right under international rules to summon Aguero -- and can carry out their own medical assessment, if necessary -- but he thinks it is a ludicrous situation.
Aguero won't even be eligible to play against Paraguay because of a suspension for yellow-card accumulation. Aguero was cautioned in Argentina's past two matches in the competition, against Colombia on Nov. 15 and Ecuador on June 2.
Aguero may play against Peru on Sept. 11.
"He can go and fly back quickly," Mancini said. "These are the rules and we need to respect them -- they are ridiculous rules."
City initially had feared a longer layoff for Aguero, who scored 30 goals last season.
Aguero was carried off after falling awkwardly after a fair tackle from Nathaniel Clyne early in City's 3-2 win over Southampton at the Etihad Stadium.
"Maybe after the international break he will be ready -- three or four weeks," Mancini said. "It's a bad knee injury but not for six months -- two or three weeks. After two weeks he can start to train maybe and in four weeks he can play, maybe.
"We are lucky with Sergio because he can be very strong after injuries."
