Diego Maradona says son-in-law Sergio Aguero has saved the reputation of Manchester City boss Roberto Mancini.
Maradona is unhappy with Mancini's treatment of Carlos Tevez this season.
"Everybody knew what kind of player Aguero was, so I'm not surprised by the level he's playing at Manchester City," he told the People.
"When he left Atletico Madrid, I knew that he was going to play for a bigger team. He could have played for Chelsea or Real Madrid.
"Mancini has a better CV thanks to Aguero. He is making the difference at a team like City, in which the cheapest player costs £40million."
