Diego Maradona is pushing for Manchester City striker Sergio Aguero to move to Real Madrid.
Maradona is Aguero's father-in-law.
"Kun (Aguero) has to play for Madrid. Even though he is flying at City, the best thing would have been to sign for Madrid. He made a mistake.
"If Madrid want someone, they get them. Florentino has no limits. It's a question of convincing City but not with money because they have plenty of that," said Maradona.
