Despite their seemingly untouchable status in Jurgen Klopp's first XI, Liverpool's forwards have been linked with moves away from the Premier League leaders recently.
A recent report claimed that Real Madrid have identified Mane as their number one target heading into the summer transfer window, but Dalglish does not expect the trio to be tempted by offers elsewhere.
Speaking to The Hat-Trick podcast, Dalglish said: "For them to think they can get Mane...unless, and it doesn't look like it, unless they're [Salah, Mane, Firmino] unhappy being at Liverpool which none of them seem to be.
"Eventually, like everything else, they'll [the team] change around a little bit, but I cannot see them getting their players. Until, and unless, Liverpool want them out rather than they want out."
Salah, Mane and Firmino have registered a combined total of 38 goals for the Reds as they sit 25 points clear at the top of the Premier League table amid the coronavirus postponement.
