Aguero, 24, admits he has been impressed by the way his countryman has performed in pre-season.
The pair barely played together last season due to the problems Tevez had but look set to team up regularly this term.
"I'm happy for Carlos. He's looking after himself a lot.
"The goal was very good. I was next to him saying 'Carlos, Carlos, Carlos'... I was asking him.
"Then I thought he was going to shoot and he let out that strike. A fantastic goal. "
