"I don't know whether Inter were a cursed club when I arrived," Mancio said. "But I realised that it was a complicated situation because there's no other way to explain a squad with so many champions failing to win anything for such a long time.
"I didn't waste time asking myself what was wrong and I started at once working to try and understand what had happened.
"There were so many things that weren't working on and off the pitch. It was a mission for me. It wouldn't have been stimulating to take charge of a team that had always been winning.
"The development of this side is something that I have worked hard for with everyone's help. The players have changed direction and understood that they need to step up if they are to win something serious."
Inter's recent achievements have been tainted by constant controversy and accusations of refereeing bias - a situation that Mancini has grown weary of.
"People live for this debate in Italy," he explained. "There are lots of people who just dedicate their evenings to watching videos and looking to create chaos.
"They are no use to anyone because they don't relate to reality. Referees don't have the use of cameras.
"I used to watch all the highlights on TV, but for 10 years I haven't watched a football programme because they disgust me."
