The Portugal international volleyed home his fourth goal in five games in the 1-0 win at Chelsea, providing further evidence of his growing influence.
"Understandably Raul has been getting some headlines for the goals he's scored in recent weeks," said Dalglish for his LFC Weekly column.
"His performances have been what I've expected. I knew he was a good footballer before he came to the club and he's shown that.
"He's intelligent and very good technically; he puts in a pile of running too. He's getting on the scoresheet so often because he's playing a bit further forward. Those goals are a huge bonus for us.
"The strike on Sunday wasn't as easy as it looked. He had to get up and over the ball to make sure he knocked it inside the post.
"The great thing for us was we had players getting into the box to capitalise on chances like that."
