Mo Salah is fast becoming one of my favorites due to his performances so far this season for Liverpool.
However my all time favorite for the moment has to be Luis Suarez, he's a controversial figure due to some of his antics including hand balls and biting opponents but I have always admired his work ethic.
Suarez is nowhere near the most skilled player or technically gifted but he works harder and puts more into trying to win every game than any other player I have seen.
