The Brazilian now has six league assists to his name since moving to England in 2017.
He overtakes Paul Robinson, who picked up five assists across his top-flight career with Leeds United, Tottenham Hotspur, Blackburn Rovers and Burnley.
Our man is up to three in this campaign alone, which also sets a new record - with several goalkeepers previously notching two in the same term.
As well as his three assists this term, he also supplied his team-mates once each in 2018/19, 2020/21 and 2022/23.
Three of his assists have teed up Erling Haaland, while he’s also supplied Sergio Aguero and Ilkay Gundogan before the sixth pass for Marmoush.
Speaking on Saturday after breaking the record, Ederson was typically humble.
He said: “I’m happy to make this mark. I hope there is more to come.
“It’s a difficult team to play against because they mark man to man. I see the space, because they go man for man, the player free is the goalkeeper.
“Up front they’re man for man and we have good fast players, Savinho, Marmoush and Erling, so it’s easy, I just put the ball there.
A revolutionary goalkeeper, Ederson’s ability with the ball at his feet has been a crucial part of our historic success under Pep Guardiola.
Remarkably composed in the face of high pressure from opponents, he often opts for short, incisive passes to the backline.
However, he’s equally capable of picking out a player further up the pitch or - as in the case with Marmoush’s goal here - sending a striker in behind.
He’s done so for the likes of Sergio Aguero, Ilkay Gundogan and Erling Haaland in the past, but Marmoush was the beneficiary of our No.31’s vision this time around.
That’s not to take away from his reliability when it comes to shot stopping and his bravery in sweeping up behind the line.
With six Premier League titles and three Golden Gloves, this latest record cements his status as one of the division’s greatest ever goalkeepers.
Congratulations to Ederson on this latest landmark in an incredible career!
