The Egyptian attacker has made a scintillating start to the 2021-22 season and already has 14 goals and four assists to his name from 11 games in all tournaments this term.
Salah has also found the net in both of his most recent games at Old Trafford - scoring twice in a 3-2 FA Cup fourth-round defeat before netting once in a 4-2 Premier League win back in May.
Should Salah make the net ripple in Sunday's clash, he will become the first player in Liverpool history to score in three games in a row away to Man United across all competitions.
The Reds will also be out to equal a goalscoring feat this weekend, as they can go level with Manchester United's record of scoring at least three goals in six Premier League away games on the spin.
Salah also recently affirmed that he wants to remain at Liverpool for the rest of his career, with his existing deal due to expire in 2023.
