Salomon Kalou admits he has not scored enough goals since joining Chelsea.
Kalou ended a personal drought dating back to November when he finally netted his 50th for the club in Sunday's FA Cup third-round thrashing of Ipswich.
It took the 25-year-old four and a half years and 210 appearances to reach the milestone, something he accepts is not good enough, especially with Chelsea crying out for a consistent goalscorer during their worst slump in the Barclays Premier League for almost 15 years.
"To be honest with you, every game I play with Chelsea, I come out of it with regret because I feel like I should have scored another goal," the Ivory Coast international told his club's official magazine, Chelsea.
"(My coach growing up) Jean-Marc Guillou always used to say, 'The most difficult thing is not knowing how to score but knowing how to create yourself a chance'.
"I know that I can create chances for myself, I do it every game and now I just have to concentrate on putting more of them in the net."
