The Liverpool forward’s second finish of the afternoon at London Stadium was the culmination of a precise Reds counter-attack.
Xherdan Shaqiri moved onto Trent Alexander-Arnold’s crossfield pass and lifted it into the penalty area, where Salah instantly controlled the ball and then pushed it into the bottom corner.
The Egyptian’s effort - which also claimed the LFC Goal of the Month prize - was subsequently voted the best in the division during January, coming out on top from a shortlist of eight.
Salah said: "Thank you. I think it was an important goal also for us because I think that goal was [the] second goal, so it helped us to just relax a little bit.
"That's a team goal because it started at a corner against us. Robbo headed it at first, then Trent, then Trent to Shaq and Shaq to me, so it was a team goal.
"So it's a great feeling to score goals like that but the most important thing is that we won the game. That's what makes the goal so special."
