Ederson added: “I arrived in Manchester eight years ago full of hope, but I could not have predicted such a beautiful time together.
“Playing for City has been the most special time of my life and I will always be a fan of this special club.
“I’m going with my wife and children, but I’m leaving a big family here, Cityzens. Once a Blue, always a Blue.”
Not only did Ederson claim 122 clean sheets from 276 Premier League appearances, but he also registered seven assists in the competition.
Former Liverpool player Bruce Grobbelaar is the only other keeper to have won six English top-flight titles.
“The fact no goalkeeper has ever won more Premier League titles says everything you need to know about his quality and consistency in a City shirt,” said City’s director of football Hugo Viana.
“He has been a huge figure in all our successes over recent years, and his skills and bravery have been crucial in helping City play the beautiful football we have seen. He has truly cemented his place in the history of Manchester City.”
