The former Liverpool star has made just two substitute appearances for the Potters since joining on a free from Manchester United and Sorensen feels there has been enough in his cameos to indicate that he will begin to hit the target when he gains full match fitness.
"He has not had the start that we have been through and has been training on his own, so he has little to catch up," Sorensen told Onside.dk.
"But of course you can see his qualities, and I also believe that he has the confidence of the coach.
"So he'll get chances, and then he'll strike. I'm sure."
