The former Blackpool midfielder played a part in both goals as the Reds beat Chelsea at Stamford Bridge and wants to "push onwards and upwards" according to his coach
Adam was involved in both goals as Dalglish's side took an important three points, starting the move for Maxi Rodriguez's first before playing the decisive pass that led to Glen Johnson's winning effort.
"He's only endorsed what we thought when he arrived," he told Liverpool's official website.
"Charlie played very well but there's nothing he's doing that has surprised us.
"He covered a fair bit of ground. He won the ball back on many occasions during the game, but that one for the first goal was highlighted more because it resulted in us scoring.
"His pass for the second goal was sublime as well."
Dalglish added that he hoped Liverpool supporters were yet to see the best of Adam.
"He was someone we wanted to get in January but it didn't happen," he said. "We were patient and got a discount on him in the summer.
"I don't think it's been a bad bit of business. I don't think he will rest on his laurels either. He wants to push onwards and upwards and so do we."
The 60-year old also spoke on the upcoming return of Craig Bellamy to former club Manchester City.
Bellamy spent a season in the Championship with Cardiff City while out of favour at the Etihad Stadium but Dalglish was confident the Welshman would approach it like any other game when the two clash.
"Craig Bellamy is a fantastic professional footballer as we said after the game on Sunday," he said.
"He knows his profession. He knows how to get himself prepared for a game. He's been a huge plus for us since he came in. What happened elsewhere for Craig at other times in his career, doesn't really concern me.
"We've been absolutely delighted with the way he has gone about his work on and off the pitch since he came here."
