The Clarets impressed for the 1-1 draw, but Dyche was impressed most by the Brazil international.
"I could not believe it, almost ...," Dyche said of Ederson conceding to Johann Berg Gudmundsson.
"I thought: my God, he's going to save it too. He's the calmest goalkeeper I've ever seen. It's like you've got Ronald Koeman in goal, he gets the ball, does everything on the field and plays great balls.
"He adds incredibly much to the game of Manchester City, because he dismantles the game (from the opponent). They often go back to him. He is so good and calm. He just looks for someone in the midfield or someone on the wing, there are not many keepers who can do that, it's a huge weapon for them."
