Egyptian winger Mohammed Salah paid tribute to former national teammate Moamen Zakaria following his hattrick against Leeds United on Saturday.
Salah adopted a new celebration attributed by the former Roma man, pressing his hand over his ears after his third goal - and the reason has now been explained.
Salah's actions were a tribute to his international teammate Moamen Zakaria, emulating his friend's customary celebration; the player suffering from Amyotrophic Lateral Sclerosis (ALS), commonly known as Motor Neurone Disease, which affects the brain and spinal cord.
And to explain the celebration, Egyptian journalist Mohamed Adam told the Liverpool Echo: "Much of the Egyptian media is talking about this.
"(Zakaria) is a friend of Salah and everyone in the Egyptian football world is feeling for him."
On Friday evening, teammates of Zakaria's at Egyptian outfit Al Ahly also showed solidarity as they reproduced his celebration following a 3-0 victory over Ismaily.
