Jota has hit the ground running at Liverpool since his arrival from Wolves.
Dalglish told the Liverpool Echo: "For Diogo to come in and score as freely as he has done and to make such an impact, not always having played the full game, will do him a world of good.
"The belief he'll have in himself and the confidence supporters will have in him too.
"It's important when someone comes in and settles straight away, for the player and the club, just look at the contribution he has made.
"I'm not particularly concerned about Firmino. Bobby [Firmino] is a great player with a great touch and gets through an awful lot of work. He compliments Mo [Salah] and Sadio [Mane] when the three of them play together, and obviously the four of them played together at City and were really good together.
"Bobby [Firmino] is a really important player for Liverpool."
