Man City's No 1 has two more clean sheets than Chelsea's Edouard Mendy, with both players having four matches remaining.
If Ederson manages a shutout in this weekend's duel at the Etihad Stadium and Mendy concedes a goal, the Brazilian's total of 19 clean sheets cannot be beaten.
Having won last season's award with 16 shutouts, Ederson would become only the third goalkeeper to win the prize in successive campaigns, after Liverpool’s Pepe Reina and former Man City shot-stopper Joe Hart.

Ederson and Mendy go into their meeting in strong form, having each kept a clean sheet in their last Premier League match, with Man City beating Crystal Palace 2-0 and Chelsea overcoming Fulham by the same scoreline.
While Mendy is in second place, his tally of 16 clean sheets is impressive given he had to wait until October for his PL debut and has only played 28 matches this season, five fewer than Ederson.
Martinez will need to keep a clean sheet in at least four of his remaining five outings to maintain his challenge, and even that may not be enough.
While the Golden Glove could move out of reach, Martinez has every chance of beating Villa's club record of 15 clean sheets in a single Premier League campaign.
