Hart was modest when asked to reflect on his own performance, which had many including England team-mate Wayne Rooney hailing him as the world's best goalkeeper.
The 25-year-old said: "It's nice to make saves, it is not something I have to do a great deal at City but when required I try to step in and I was required a few times."
Hart is yet to keep a clean sheet for City this season and the defence, a considerable strength last season, has become a concern.
Hart said: "We were pretty open but it allows us to play forward.
"Hopefully we can shore it up again and be the force that we are."
