The goalkeeper was in fine form at the City of Manchester Stadium, repelling numerous efforts - most notably four one-on-ones with home striker Paulo Wanchope and a rasping effort from Steve McManaman.
With a clean sheet and a point in the bag, Kasey can reflect on his performance with a degree of satisfaction.
"It was a good game for me and I was happy," he responded in an understated manner. "Last season I had a couple of good games and we conceded late penalties - at Bolton, Man Utd... I hate remembering good games and losing, it is always nice to come up with a few saves and at least collect a point out of it."
Kasey lamented after the defeat at Chelsea the amount of times he was left one-on-one with the striker. This did happen against City but he reasoned that the danger was easier to avert.
"I had four I think, but there was a bit more pressure on the guys going through and better angles for myself to make the saves. When Paulo came through a couple of times he was wide and it makes it so much easier.
"Mutu was coming inside for Chelsea, which gives him so much more to shoot at than Paulo coming outside.
"A lot of credit to us, we hung in there and got the point. They picked up the pace in the second half - but we can't complain about two clean sheets in a row."
Kasey Keller did not disagree with the suggestion that his performance against Manchester City must be up there with his personal bests.
