Kozak hit the winner at Norwich City after coming off the bench for his injured teammate.
Kozak said: "Christian has scored many goals and I hope I can help the team and score some more. It was important on Saturday and now we're thinking about tonight (against Tottenham).
"I want to score in all of the games.
"That's a dream and the more goals the better. It was important to score early. I don't know how long Christian will be out for."
