There's a reason Mohamed Salah starts virtually every match for Liverpool, and it goes beyond pure ability. Jurgen Klopp has five elite offensive options to use at Anfield yet virtually every week, it is Sadio Mane, Luis Diaz, Diogo Jota and Roberto Firmino who rotate among each other.
Unlike his four attacking teammates, Salah is crucially left-footed. With the exception of Harvey Elliott and Kaide Gordon - both of whom are teenagers - he is the only Liverpool player in midfield and attack who prefers to use his left foot ahead of his right.
As a result, he is arguably the most difficult to replace in terms of the dynamic that he adds when he's on the field. Left-footed forwards who are quick, goal-orientated and capable of reaching a high ceiling aren't particularly common, although the Reds will come up against one in their next match.
