#5 Mohamed Salah (Liverpool)
As good as last season started for him, this season has unfolded astoundingly poorly for Salah. The forward has been the weakest link in Liverpool's potent attack, Sadio Mane and Roberto Firmino carrying them up the league table.
Salah has looked hesitant, nervous, and sluggish. It has to be said that he still appears to be carrying an injury, with heavy strapping still noticed across his shoulder during every game, but the star of 2017/2018 has evaporated.
Many have foolishly been quick to label him a one-season wonder, which entirely ignores his superb form for Roma for two seasons prior to arriving at Anfield; last season's freakish goal numbers was always likely to be tremendously difficult to reach anyway.
Ever since Sergio Ramos's challenge on him in the Champions League final last May, Salah's success story has been fading. A poor showing for his country Egypt at the World Cup didn't help matters.
His manager Jurgen Klopp hasn't appeared too worried about his player, trusting that his form will return and Salah can point to still having three goals in the league so far. If Liverpool are to win a first league title in 28 years, however, Salah will need to raise his performances quickly.
