Roberto Mancini admits that he is as surprised as anyone over his return as Inter coach and says that he has "everything to lose", six years after leaving the club.
The 49-year-old won three successive Serie A titles in his first spell at the San Siro but was sacked by former Nerazzurri president Massimo Moratti in 2008.
Following an indifferent start to the 2014-15 campaign, Inter parted company with Walter Mazzarri on Friday, paving the way for Mancini's appointment.
"I was very pleased to receive the affection of the fans," the returning boss told reporters.
"I never thought I'd come back to Inter but it all happened so quickly. These things can happen in football.
"I honestly never thought I'd return here as, when you've done good work, then there's everything to lose by coming back.
"I was called, the project was explained to me and I think it can be another great story," added Mancini, who most recently endured a disappointing spell in Turkey with Galatasaray.
"I hope we can repeat what we achieved 10 years ago. It's tough to say if there are comparisons, but this team looks like it has quality - as we did a decade ago - and we just need a bit of luck, to work together and ensure things don't get worse.
"It's down to us now to restore enthusiasm and bring the fans back to the stadium so we can get back to winning ways.
Mancini's first game in charge will come against rivals AC Milan on November 23.
