VIDEO: 'Unai is a world-class coach' - Klopp

Liverpool face Villarreal at Anfield this Wednesday. It will be the first leg of their Champions League semi-final tie and kick off is at 21:00 CET.

In the knockout rounds leading up to this stage of the competition, Liverpool have overcome Inter Milan (2-1 on aggregate) and Benfica (6-4 on aggregate). Their semi final opponents have shocked two European giants on their way to this year's semis. They overcame Juventus 4-1 on aggregate, followed by Bayern Munich (2-1 on aggregate).

Jurgen Klopp does by no means see his opponents in the semis as an easy pass into the final. He knows his team are coming up against a seriously dangerous side. Have a listen to his pre match thoughts in the video here!
