The Argentina striker netted for his country in Tuesday’s friendly against Nigeria in Krasnodar.
At half-time, however, he fainted in the Albiceleste dressing room and had to be taken for hospital for routine tests.
But it appears that Aguero has made a swift recovery after the scare as he declared himself available against Leicester City.
“All the tests they run on me – just for caution – turn out well, so I’m set to go for Saturday’s match. C’mon, City!!” he wrote on Twitter.
Aguero has made a fine start to the Premier League season, scoring eight goals in as many games so far.
That form has helped Pep Guardiola’s men to the top of the table, where they enjoy an eight-point lead over nearest rivals Manchester United.
