Crystal Palace caretaker-manager Lennie Lawrence said his side just about deserved their victory at the King Power Stadium.
Lawrence, who is expected to leave the club this week to link up with former manager Dougie Freedman at Bolton, said it was a proud scalp for the Eagles to be the first side to win a league game on Leicester soil this season.
Lawrence admitted that his side rode their luck at times, but said overall their game-plan had worked to perfection.
"Leicester and Cardiff are the best home teams in this league, so we knew exactly what it would be like and drew up a game-plan," said Lawrence. "It worked for us.
"We started boldly and bravely, and this time we got our reward.
"We knew they would come at us and there would be a bombardment and a heavy spell of pressure at the start of the second half, and we defended resolutely.
"We had our chances for a third on the break and we rode our luck at times in our penalty area, and Julian Speroni produced some good saves.
"It was our day. We probably just about deserved it overall.
"It is a great scalp for the club because Leicester will be in the top six, without a shadow of a doubt.
"You can see why they are where they are. They are on the front foot and virtually everyone is committed to going forward.
"They will get caught on the break because of the way they play but, if you are not bang on it when you come here, they will sweep you aside..
"There was a shout for a penalty for them but we had enough chances to get a third as well. Perhaps we had a bit of fortune in our box.
"When they did eventually score, it a good header from Andy King. But fortunately for us, it was just too late."
