Former Manchester City goalkeeper David James hailed Ederson's performance after Saturday's 1-0 Premier League victory away to Leicester.
Ederson stepped up when it mattered to thwart Harvey Barnes and Patson Daka in either half and preserve the clean sheet.
James told City's website: “When City signed Ederson, I watched videos of him and one was at Benfica diving at someone's feet, brave as a lion.
“That's the type of guy he is, and he's proven it once again. If he doesn't show that bravery, Leicester are 1-0 up at half-time.
“He's not had much to do, but today he did everything perfectly which allowed City to get the three points against a tough Leicester side."
