Second half
After the restart, the game saw fewer clear-cut openings at either end with Palace holding the advantage.
Munoz attempted to convert a low Pino cross from a tight angle, while half-time Reds substitute Cody Gakpo fired a shot from outside the area off target.
Ahead of the hour mark, Wirtz’s run into the six-yard box was found by Szoboszlai, though he was unable to convert from in close as Henderson punched his effort away.
Shortly afterwards, Alexis Mac Allister picked out the run of Isak in the box and the striker found space with some clever play, but was unable to find the far corner with his shot.
Isak next guided a header over the bar as Liverpool pushed forward in an attempt to find a leveller, while Szoboszlai saw a low drive at goal turned over by Salah with pressure continuing in the Palace half.
Eagles substitute Nketiah glanced a header wide from a Mateta cross to serve as a reminder of the threat the hosts posed on the counter.
Chiesa was also introduced into the contest from the bench by Slot and he almost restored parity between the two teams with a curling effort that whistled the wrong side of the post with Henderson rooted to the spot.
The Italian was not to be denied his leveller, though, reacting quickest in the box after a deflected cross fell into his path to clip a low shot into the back of the net with 87 on the clock.
Both teams pushed for a decider amid stoppage time and it was Palace who produced it, Nketiah driving in a low finish when a long throw from the right reached him inside the box.
