"Mo [Mohamed Salah] is pure quality," explained Jurgen Klopp at his pre-match press conference.
"Ask him what he likes against Manchester United but the more we talk about it the less likely it is going to happen so I don't like to talk too much.
"An unbelievable player. The boys did well [without him] but it's better to have him around the pitch.
"Mo is definitely ready [for Sunday]."
Salah returned to the Liverpool starting XI earlier this week for the first time since New Year's. His return is a massive boost for the Merseysiders, who are already in great form.
Salah also has an enviable record of 12 goals against Man United and there's no doubt he will be looking to add more on Sunday.
However, Man United are boosted by Rasmus Hojlund's return. There is hope he could cause some damage as the Red Devils aim to win the FA Cup - their only chance for a trophy this season.
