Nigel Pearson was a relieved and happy man as Leicester ended Blackpool's 100% record with a 1-0 win at the King Power Stadium.
The victory also brought to an end a run of three defeats for the Foxes, who bounced back from a humiliating Capital One cup exit against Burton.
Blackpool's players protested against referee Michael Jones' decision and manager Ian Holloway accused Vardy of diving.
Leicester boss Pearson said: " We showed a bit more resilience and it was a good performance and result for us.
"I thought we deserved it. We didn't play well in mid-week and were turned over and deservedly so.
"But I was really pleased with the players.
"The bottom line was that the result in this match was always going to be more important than the performance, but I felt we played pretty well."
Angry Blackpool manager Ian Holloway said: "It was not a penalty.
"It was a hopeless decision. The boy so blatantly dived. The crowd also played their part. They shouted for something, then shouted for handball and the referee looked like he could not wait to blow his whistle."
