Adam scored only two in 40 appearances for a struggling Liverpool side and has yet to find the net since a cut-price switch to Stoke in the summer.
Pulis said: "I'm still hoping he will weigh in with eight to 10 goals. He's got the quality to do that.
"He will score soon and then he will go off on one. We're still waiting for his Blackpool scoring form.
"We've been delighted with him. He's got to relax more. He's been very uptight about it. He's so keen to prove what a good player he is."
