Liverpool host Villarreal tonight, Wednesday April 27, in the first leg of the UEFA Champions League semi-final.
Villarreal, the side nicknamed "The Yellow Submarines", have been the surprise package in this year's tournament, defeating Juventus and Bayern Munich on their route thus far. Coach Unai Emery has previously proven himself as something of a master when it comes to knock-out European competition.
Emery led Sevilla to three successive UEFA Cup titles between 2013 and 2016. He added a fourth to his personal honours list with Villarreal last season, and was also defeated in the final during his spell in England as coach of Arsenal.
