Jürgen Klopp detailed the changes made at half-time that enabled Liverpool to beat Villarreal and reach the Champions League final.
The Reds recovered from 2-0 down at the break to win the second leg 3-2 at Estadio de la Ceramica thanks to goals from Fabinho, Luis Diaz and Sadio Mane, and therefore advance 5-2 on aggregate.
Klopp has now led the club to three Champions League finals in five seasons and his team are the first side in history to reach the final of that competition, the Emirates FA Cup and Carabao Cup in the same campaign.
