A picture of Mohamed Salah when he was taking off his shirt to celebrate the goal; And the cameras spotted two muscles on the sides of the player's chest that resemble the wings of birds, in an unusual scene for football players.
The muscle aroused comments and questions from the pioneers of social networking sites; Where Salah received wholesale praise due to his terrible physical development during the recent period, in parallel with his technical brilliance and his transformation into a digital phenomenon with Liverpool.
Is this muscle an attempt to strengthen the shoulder and avoid a repeat of the previous injury to Salah's shoulder, which was caused by Real Madrid defender Sergio Ramos, in the 2018 Champions League final?
But the comments were not without wit; Where one of the followers of "Facebook" said: "It's not a muscle... it looks like someone is hugging it from behind." While another went on to say that this muscle is "like gills"; While she saw a follow-up in the photo, "Coach's Fingers" Jürgen Klopp.
However, the muscle that appears in the picture is scientifically known as the "Serratus anterior muscle", or "the anterior serratus muscle", and it connects the shoulder bones to the upper eight ribs, according to "Sky News Arabia".
The muscle is known among athletes as the "boxer's muscle", because it is responsible for extending the shoulder forward around the rib cage when one person punches another.
And in order for the muscle to reach this degree of prominence, as in Salah’s case, you need strenuous exercises for the shoulder, chest and abdomen, which include lifting weights above the head while turning the arms up.
