Liverpool host Benfica in the second leg of the Champions League Quarter Finals with Villarreal in wait for the winner of this tie.
The reds won 3-1 away at Benfica but it was a difficult night in parts, with Liverpool's finishing the difference last Tuesday.
In last night's game, Villarreal claimed a 1-1 draw at Bayern Munich - which added to their first leg 1-0 lead meant they knocked out the German Champions.
The reds played out a 2-2 draw with Man City at the weekend, and face City again on Saturday at Wembley. But Jurgen Klopp has no intention of resting players. He said he intends to pick the 'freshest' team he can for tonight's game as the reds continue their quest to collect as many trophies as possible this season.

As it happened...
Speaking ahead of tonight's clash, the Liverpool boss said:
"It is a super important game".
"We tried so hard to get to the Champions League and now we can make it to semis.
"It's 3-1 at half-time, it's as tricky as 2-0. A good basis, but if they score one - like we felt against Inter - the game changes.
"We felt it when they scored last week. We really need to make them feel this is a place they don't want to go."
Liverpool posted a perfect record in the group stage, which was widely called the 'Group of Death', before knocking out Italian champions Inter Milan in the last 16.
Lots of changes from Sunday's game against Man City. Firmino and Luis Diaz selected up front to partner Diogo Jota.
Alisson, Gomez, Matip, Konate, Tsimikas, Henderson, Milner, Keita, Diaz, Jota, Firmino.
Subs: Kelleher, Fabinho, Van Dijk, Thiago, Mane, Salah, Oxlade-Chamberlain, Jones, Robertson, Origi, Alexander-Arnold, Elliott.
It looks like just one change for Benfica from the first leg. Keeping a very strong line up.
Vlachodimos, Gilberto, Otamendi, Vertonghen, Grimaldo, Weigl, Taarabt, Ramos, Gonçalves, Soares, Núñez
Subs: Leite, Almeida, Bernardo, Morato, Dias, Lazaro, Meïte, Radonjić, Seferovic, Mário, Yaremchuk, Álvaro

Milner gets a weak foot on the ball and it spins into the area and into the path of Ramos who fires it in.
