Aymeric Laporte, who signed for City in January 2018 for a then club record fee of £57million, breaks up the Liverpool hegemony in the back four.
Virgil Van Dijk, who joined Liverpool in a record £75m transfer in the same month Laporte completed his move to City, has been a reassuring and instrumental presence in the Reds' back line.
The Dutchman will be a strong contender to win the Players' Player award and he partners Laporte at centre-back, with Alexander-Arnold and Robertson occupying the full-back berths.
Liverpool goalkeeper Alisson Becker has conceded two fewer goals and kept two more clean sheets than City counterpart and Brazilian compatriot Ederson.
But it is Ederson who takes the number one jersey with the PFA, which will honour the players at its annual awards ceremony in London on Sunday, April 28.
