Salah and Kane are huge candidates, as is Halaand and possible Nunes.
Something worth noting is that Salah and Kane each have 3 EPL golden boots and no other active player in the premier league has more than 1.
It either wins it this year, they'd tie Henry's record of 4. And if either wins the top playmaker award this year (Salah was the top assister this past year as well as the top scorer), he would be the only player in premier league history with multiple top scorer awards and top playmaker awards.
Salah has the all time record for most goals in a 38 season (32 goals), while Kane had the record for highest goalscoring ratio in a season (0.97)
