Argentina international Aguero, 23, has a 45million euros buy-out clause in his Atletico contract, which has put off a number of suitors with Juventus reportedly only prepared to bid up to 25million euros.
Real and big-spending Manchester City have the capital to match Atletico's valuation and Manzano acknowledged getting the best price was the priority.
"It is better that he (Aguero) goes to (Real) Madrid for 45 million euros than to another team for 25 million euros," Manzano said in 'El Larguero'. "You always have to look for the best value in the market."
Aguero is thought to prefer a move within Spain and has hinted at the possibility of a move to Real Madrid, but Manzano admits the door is still open for the player to change his mind.
"The player is ours at the moment and I would love to coach Kun Aguero," said Manzano. "He would be received with open arms."
