Argentina legend Diego Maradona has urged Sergio Aguero to ignore his Atletico Madrid connections and join Real Madrid, insisting such a move would represent "his big break".
Aguero, 23, spent five years at the Vicente Calderon before moving to Manchester City, where he has flourished since arriving in a £38 million deal last summer.
Real Madrid were believed to be interested in signing the former Independiente striker before he made the switch to Eastlands, though he once claimed he would never play for a team starting with the letter 'R', in reference to Racing and Real Madrid, the two bitter rivals of the clubs he has played for so far in his career.
But Maradona, whose daughter is married to Aguero, believes that his son-in-law should go back to La Liga with Real and thinks "he made a mistake" by choosing to sign for City ahead of this season.
"Kun has to play for Real Madrid. If he signed for them, it would be his big break," Maradona told Radio La Red."Even though he is flying at City, the best thing would have been to sign for Madrid. He made a mistake."
Aguero is City's top scorer this season with 16 goals and it is seems unlikely the club would entertain any bids for him, but Al Wasl coach Maradona believes Real president Florentino Perez would be able to convince the current Premier League leaders to sell.
"Now, as he is doing so well, it will be difficult to get him from City. They will want to keep him because [Roberto] Mancini has him very much in his plans," Maradona said.
"However, 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.
"If Kun was playing for Madrid they would close in further on Barcelona. We would be talking about Cristiano Ronaldo scoring 60 and more goals, because Kun would move the entire defence."
