The striker saw his second-half header clawed from underneath the bar by Chelsea goalkeeper Petr Cech, while replays were unable to confirm whether the ball crossed the line
The England international had provided a lifeline for Liverpool after netting in the second half to cut Chelsea's two-goal advantage but saw his subsequent header from a Luis Suarez cross clawed from underneath the bar by Petr Cech.
Dalglish admits his initial reaction was that the goal should have been awarded but concedes he has not seen the incident again since.
"There's no television in there so I don't know I haven't seen it," Dalglish told ITV.
"I thought it'd gone in but that's not me judging if it's gone over the line or not. If it hasn't gone over the line then I'll give the officials the credit they deserve.
"I've not seen it bounce I've not seen where it landed or whatever. I'm working on the presumption that some people might have given it some wouldn't. If it had of gone in who knows what might have happened, but it didn't.
"It's one of those, it could have been called either way."
Chelsea raced into the lead after 11 minutes through Ramires before doubling their tally after the break through Didier Drogba.
Dalglish claims his players were aware of Chelsea's game plan but admitted Roberto Di Matteo's side were the stronger side for the majority of the tie.
"They were better than us for the first hour," said Dalglish.
"They scored a goal and then suddenly get a great block from a volley from Craig Bellamy immediately after it. We finished fairly strongly after going 2-0 down and if we started the way that we finished we may be a bit happier than we are now.
"Certainly they played the way we expected them to play, just sit, well, take it off us counter attack come at us, and that's what they did."
Despite the defeat, Dalglish was buoyed by his side's response after going two goals behind and feels Liverpool could have secured a different outcome if they started stronger.
"We'll assess the season at the end of the season," he said.
"I think that we finished the game very strongly and had we gone into the game with that pace and commitment then we might have got a better score."
