Liverpool booked their place in the Carabao Cup final after producing a dominant display to turn around the semi-final against Tottenham.
Having trailed 1-0 from the first leg, Arne Slot's side brushed aside the visitors at Anfield to set a clash with Newcastle next month at Wembley.
Gakpo pulled Liverpool level in the tie in the 34th minute, with the Dutch forward firing a first time finish beyond Tottenham goalkeeper Antonin Kinsky.
Salah put the Reds ahead in the tie from the penalty spot in the second half after Kinsky brought down Darwin Nunez in the box.
