The Liverpool duo are shortlisted alongside Sergio Aguero (Manchester City), Abdoulaye Doucoure (Watford), Jack Grealish (Aston Villa), Ayoze Perez (Leicester City) and Jack Stephens (Southampton) for the accolade.
Henderson was in fine form in central midfield during the month and captained the Reds to five straight victories in the top flight, including a goal against Wolverhampton Wanderers.
Alisson, meanwhile, recorded four clean sheets between the sticks – the third of which came against Manchester United when he also provided an assist for Mohamed Salah.
