On 19 August 2018, Ederson became the first Manchester City goalkeeper to provide a Premier League assist, as his goal-kick was converted by Sergio Agüero for the opening goal in a 6–1 win over Huddersfield Town.
Ederson was named in Brazil's provisional squad for Copa América Centenario but was cut from the final squad due to injury. His debut for the national team came in a 3–0 win over Chile in a 2018 World Cup qualifier in October 2017. In May 2018, he was named in Tite's final 23-man squad for the World Cup in Russia.
Ederson has been described as an agile, commanding, and physically imposing keeper, who possesses both physical strength and excellent reflexes and shot-stopping abilities between the posts. He also developed a reputation as a penalty saving specialist during his time with Benfica. However, he is mostly highly regarded for his outstanding distribution and skill with the ball at his feet: his control and confidence on the ball enables him to retain possession and quickly play the ball out from the back on the ground with his hands or either foot – even when put under pressure – or launch an attack with long kicks. Although naturally left-footed, he is capable of using either foot. Regarding his distribution, former Manchester City goalkeeper Shay Given described Ederson as "the best goalkeeper in the world with his feet" in 2018; his range of passing has also led to him be described as a playmaker in the media.
