Mancini claims the success being enjoyed by Capello's successor, Roy Hodgson, would not have been possible were it not for the efforts of the previous incumbent.
"England has to thank Capello," Mancini said. "I've seen them playing and I recognise his organisation.
"I understand that this England play in a way that could seem boring, but at this point of the season, every player is tired and from this match the team who score first could win with a high percentage.
"So Hodgson needed to work on the defence and improve this part of the game. He is smart because, in this short time, a revolution would not work. He follows the work of Capello and, at the end of the day, he is an English-Italian coach."
