The 31-year-old scored four goals in Saturday’s 7-1 thrashing over Aston Villa which means he is now the third highest goalscorer in Chelsea’s history.
"I'm very proud. I've passed Peter Osgood, I took a few more games, but I'm very honoured to be among those sort of names," Lampard told BBC Sport.
Two of Lampard’s goals came from the penalty spot and the England midfielder says after missing penalties in training, he had to put power in his spot-kicks if he was to beat a keeper of Brad Friedel’s quality.
Lampard added: "I missed a couple of penalties in training on Friday and I know Brad Friedel is a top keeper and they can save them if they go the right way, so I wanted to put my foot through it."
Since joining Chelsea from West Ham United in 2001, Lampard has scored 151 goals for the club.
Saturday’s four goals took his tally for the season to 21 which means he has now scored at least 20 goals in each of the last five seasons.
