Liverpool host the first leg of their Champions League semi-final vs Villareal on Wednesday night at Anfield.
The last time the two teams met was in the Europa League semi-final in 2016 when Liverpool beat the Spanish outfit 3-1 on aggregate to secure their spot in the final against Sevilla.
Sevilla won that match 3-1 and were managed by current Villarreal boss Unai Emery.
Reds manager Jurgen Klopp, who confirmed that Roberto Firmino is likely to miss the first leg through injury, has huge respect for Emery and his side.
Klopp said: "We have properly analysed Villarreal. I have proper respect for Unai and them. I watched them properly and wow! Impressive. He is a detail-obsessed manager. Different ways to press and react to different results. A world-class coach doing an incredible job."
