While Tevez endured his struggles during four eventful years at the Etihad Stadium, his arrival helped to spark a surge which carried the Blues to FA Cup and Premier League triumphs.
He decided to move on during the summer transfer window, with Serie A champions Juventus taking him to Italy.
Aguero admits his fellow Argentine will be 'missed' at City, but feels deals for Alvaro Negredo, Stevan Jovetic, Jesus Navas, Fernandinho and Martin Demichelis have City in better shape to push for more silverware in 2013/14.
He said in The Sun: "Carlitos has moved on and he was a great team-mate.
"He's going to be missed but we wish him the best in his next step.
"But I always keep a close eye on Spanish football and Jesus Navas and Alvaro Negredo were two of its brightest stars.
"Having them in our side makes us stronger - the same applies to Fernandinho and Stevan. They are amazing players."
