The attacker put the Reds ahead in their Group E match against Sevilla with a deflected goal in the 37th minute to make the scoreline 2-1 for the Premier League side.
His goal against Sevilla means it is the first time an Egyptian player has scored on his Champions League debut for two different sides.

But, while Salah was setting good marks, his team-mate Roberto Firmino picked up an inglorious distinction as well on Wednesday.
While Firmino got Liverpool on the board with a first-half equaliser, he also missed a penalty late in the half which would have doubled the Reds’ lead.
That missed penalty was the first in the Champions League for Liverpool in nearly a decade, when club legend Steven Gerrard missed from the spot against Marseille in December 2007.

Prior to that, Firmino's goal meant he became the sixth player to score on his Champions League debut for Liverpool.

And that exclusive club added a seventh member when Salah scored his historic goal.
