The young forward is currently fighting to regain his fitness in time to play against his former club, having made a £35 million move to Merseyside in the winter transfer window.
And the Scot insists that an adverse reception from the travelling band of supporters would mean that they considered him an important part of the club prior to his departure.
"They will react in whatever way they want and it is a compliment in a strange way, if you do get abuse, because it means you must have been important to them," Dalglish said, according to The Mirror.
"I think the boy is expecting something, but it won’t take away from what he has done for their football club and it won’t take away what the football club meant to Andy. I don’t know what they will do on Sunday but if, as a player, you don’t get abuse off your old supporters then they can’t have been too disappointed you left.
"I’m sure when Newcastle signed Alan Shearer they didn’t give too much consideration to Blackburn Rovers fans, but that’s football. What goes around comes around."
But there is a chance that the 22-year-old may not be able to feature against his former employers, but the manager is looking at the big picture.
"We’ve been delighted with the way he’s gone about his rehabilitation and his performances in the games. Unfortunately after scoring the two goals against Manchester City he picked up an injury so we just have to wait and see if he is going to play on Sunday.
"If he’s not fit then he will be fit for the next game. He’s got a bit of mileage left to go in this season yet.
