Liverpool FC will be boosted by the return of defender Mamadou Sakho in order to help stop the danger posed by the Watford defence, although Vice Captain James Milner is ruled out for the tie.
Liverpool FC face Watford looking to move past the points lost against Newcastle United and West Brom.
The Reds will be welcoming back to action French international defender Mamadou Sakho. Sakho has been missing since November, when in the game against Crystal Palace, he injured his knee.
Klopp was quoted as saying by Liverpoolfc.com: a Mamadou has trained completely normally.
.
a It is a good situation. He started normal training last week and now he has completed this week. If it stays like this he will be ready.
a Now hea s had many weeks out, everything is different, but when we all work together as a team it is easier for the centre-halves to play a normal game.
a We want Mamadoua s quality and his strength but the team has to help him too.a
The return of the French international comes at a time when the defensive crisis at Anfield is starting to deepen, following an injury to Croatian international Dejan Lovren.
Defender Jon Flanagan has also returned to training on Friday, but it is unlikely that he will be fit any time soon, following a lengthy spell on the sideline.
One blow to Liverpool FC would be the calf injury suffered by James Milner. The Liverpool FC vice-captain will make way for Lucas Leiva, with captain Jordan Henderson looking likely to continue his role in the central midfield.
Christian Benteke is expected to be overlooked, despite the absence of forward Daniel Sturridge, with Roberto Firmino taking his place in the starting XI.
