Hart, who has stepped up from his role with the club's youth teams to take over from Tony Adams on a temporary basis, fell short of nominating himself as a permanent successor but did appear enthused about being back in the hotseat.
"The thing is, I was brought here to the youth development programme and I really enjoy that," said Hart.
"But there was a little bit of a tingle in my stomach today that I haven't felt for four or five years.
Asked about any longer-term aspirations, Hart added: "I'm not looking that far. We're planning for next week, doing the training programmes and then we'll see what happens. It's not in my hands really.
"But I'm here, everyone knows where I am. I was asked to step in at a difficult moment for the club and I've been happy to do that."
Hart, whose side made a City team bulging with the attacking flair of Robinho, Elano, Craig Bellamy and Stephen Ireland look pedestrian, was also impressed by the resolve his side showed after a trying week.
"Because I've not been around management for a few years it was a day of not really knowing what to expect. Working with the players for just a day you don't get to see them at full belt.
"You wonder 'have you got this right?' that sort of thing. But I saw it in the players' eyes that they were determined and I felt comforted by that."
