In an entertaining contest, Alexis Mac Allister gave the Reds an early lead courtesy of a thumping first-time finish from Rio Ngumoha’s pass across the edge of the area.
Cody Gakpo doubled the home team’s lead soon after the interval with a drive across goal inside the box, but Conor Gallagher nodded in a corner from close range to get Spurs back into the tie.
However, a stunning long-range strike from Szoboszlai in stoppage-time secured Liverpool’s place in Wednesday’s draw for the next stage of the tournament.
