Liverpool forward Mohamed Salah honoured Al Ahly midfielder Moamen Zakaria with his celebration after scoring a hat-trick in the Reds' 4-3 victory over Leeds United.
After securing maximum points for Jurgen Klopp's men in their opening Premier League fixture with his 88th-minute strike from the penalty spot, the Egypt international imitated Zakaria's celebration by pulling his tongue out and putting his hands on his ears.
Zakaria was diagnosed with Amyotrophic lateral sclerosis (ALS) last month, a disease that affects nerve cells in the brain and spinal cord and he will not be able to play football again.
