Atletico Madrid coach Manzano hopes to keep Aguero
The Argentina forward has expressed his desire to leave Atletico and has been heavily linked with cross-town rivals Real.
Manzano, however, was hopeful Diego Maradona's son-in-law might stay.
He said: "So far the club have not received any official offer for Aguero.
"I would love to add Aguero to a long list of great players I have coached."
