Liverpool have proved to be a different team under Klopp and that has not been proved twice or three times but rather on several occasions.
With Vilarreal having a one goal advantage, The Reds were on level barely 20 minutes before half time courtesy of an own goal from Bruno.
The second half so the Liverpool side press for more goals which saw the goal machine Sturridge score from a closer ranger and later Lallana making the Yellow Submarines sink more with a third goal.
Reds will now face the defending champions, Sevilla who are out to defend it on the third straight wins.
The Spanish giants were also forced to score three more goals to cancel the Shakhtar Donetsk one advantage away goal. They later won on a 5-3 aggregate.
The winner of this Europa League cup qualifies automatically for a Champions League spot.
