The Senegal forward debuted the move after striking in the UEFA Super Cup victory over Chelsea in Istanbul last month.
The subsequent post on his official Instagram account drew a tongue-in-cheek response from Firmino, who wrote: ‘Sadio, don’t copy me please.’
However, Mane has confirmed his intentions to stick with the celebration throughout the season.
He told Complex: “Each player in this squad, if you want to keep this celebration as your own it’s quite difficult because we score quite a lot!
“Bobby did that celebration two or three years ago, and I think he has had quite a few celebrations since.
