El Zhar netted Liverpool's first in their 2-1 Carling Cup victory over Cardiff on Wednesday with a spectacular 25-yard effort.
"It was a big dream to score in front of the Kop and now I am living that dream," said El Zhar.
"I don't know if I have scored a better one than that and I hope it is the first of many in a Liverpool shirt.
"I don't have the words to describe the feeling when I scored, it was simply amazing. It happened so quickly.
"You have to forget about the big names you are playing with and try to show people what you can do. I hope I did that.
"But I now have to try to keep at this level. I must get up in the morning, go to training and continue working hard. I scored but I have got more work to do to play in this team.
"I have to keep my feet on the ground. All I've done is score - I haven't done anything in this team yet."
