Salah got his name on the scoresheet for Liverpool's fourth goal, and he will be hoping he can repeat this at The Hawthorns on Sunday in a must-win game.
Their opponents West Brom have already been relegated, and with a top four finish still on the cards for Liverpool they have a lot more at stake for this fixture.
Liverpool are clear favourites to win this game and, with West Brom having a leaky defence all season, Skybet are offering decent odds at 3/1 for Salah to score a brace.
The last three Premier League fixtures between these two sides have ended in a draw.
Mo Salah has played against West Brom five times, but is yet to feature in a winning side against them (drawn four, lost one).
Salah also has two goals against The Baggies, both of which came in 2018.
Here, we take a closer look at the last three matches Salah has played against West Brom:
Liverpool 2-3 West Brom (January 27, 2018)
In the FA Cup fourth round a five-goal thriller ended with West Brom progressing through in a game which was overshadowed by VAR controversy.
Firmino opened the scoring early with a delightful chip following a Salah chance, but the lead didn't last long with West Brom scoring two goals in quick succession by the eleventh minute.
The rest of the first half was full of drama, with VAR awarding Liverpool a penalty for a foul on Salah. The penalty wassubsequently missed before West Brom had a third goal ruled out by VAR.
A Joel Matip own goal meant West Brom did get their third goal before half time, and Salah's second half strike was not enough for the Reds to earn a replay.
Salah took the goal well with his quick-thinking allowing him to be first to a loose ball in the box, and he picked out the bottom left corner with a curling shot.
The entire game was chaotic but, despite his side going out, Salah played well and was probably Liverpool's best player on the day.
West Brom 2-2 Liverpool (April 21, 2018)
Despite going two goals up, West Brom fought hard to take a point from Liverpool, although it understandably didn't go down well with Reds boss Jurgen Klopp.
Danny Ings opened the scoring for the visitors, and in the 72nd minute Salah looked to have secured the win for the Reds as he chipped Ben Foster following a pass by Alex Oxlade- Chamberlian.
But West Brom had other ideas, and two late goals from Jake Livermore and Salomon Rondon meant that the spoils were shared.
Despite the disappointing result, Salah played well and was Liverpool's highest rated player on the day with a 7.7 rating on WhoScored.com.
The comeback was described as "useless" by Klopp as West Brom were already heading for relegation, a similar scenario to this weekend's match-up...
Liverpool 1-1 West Brom (December 27, 2020)
The last time these two met they were once again inseparable thanks to a dramatic late equaliser by The Baggies.
Liverpool took the lead early on through Sadio Mane, but a 89th minute goal from defender Semi Ajayi earned Sam Allardyce his first point as West Brom boss.
Liverpool had the majority of chances throughout the game, but Salah was well short of his best as he completed just one dribble during the contest, and none of his three shots never came close to threatening the goal.
It is also worth noting that Liverpool enjoyed an enormous 78% of possession in this fixture, but failed to capitalise on their chances which allowed West Brom to stay in the game.
This weekend, Salah will be hoping he can end his winless run against West Brom and help his side earn a much needed three points.
