Argentina legend Diego Maradona has told son-in-law Sergio Aguero to quit Manchester City and join Real Madrid in the summer.
Aguero has been a revelation since moving to the Etihad from Atletico Madrid for £38million, but has been linked with a move back to La Liga.
Newspaper reports earlier this week suggested Real boss Jose Mourinho was lining up a possible swap deal with Gonzalo Higuain to take 'Kun' to the Bernabeu.
Maradona says Aguero, who has scored 17 goals during his debut campaign in the Premier League, made a mistake by joining City and has urged him to leave for Madrid at the end of the season.
"Kun has to play for Real Madrid. Even though he is flying at City, the best thing would have been to sign for Madrid," he told Radio de la Red. "He made a mistake.
"Now, as he is doing so well, it will be difficult to get him from City. However if Madrid want someone, they get them. Florentino [Perez] has no limits.
"It's a question of convincing City - but not with money because they have plenty of that."
Aguero is currently sidelined with a foot injury and is expected to miss this weekend's trip to Emirates Stadium to face Arsenal.
Without their top scorer, City slipped five points behind Manchester United in the Premier League title race after drawing 3-3 with Sunderland on Saturday.
