The Egyptian scored the Reds' third in their 3-0 victory at Old Trafford by applying a first-time finish to Dominik Szoboszlai's pass.
The effort came out on top in a fan poll on Liverpoolfc.com – just ahead of Luis Diaz's second in the Premier League victory.
Diaz also took third spot with the counter-attacking goal versus Brentford, while opening-day efforts from Salah and Diogo Jota at Ipswich Town completed the top five.
