On 2 November 2017, Éder signed a contract extension, penning a new deal until June 2021. Only three days later, he came off the bench to score his first 2017–18 season goal in the 1–1 draw against Torino to help Inter remain undefeated. Éder made his first starts of the 2017–18 season later in February 2018, profiting from Icardi's injury; the first was in the 1–1 draw versus Crotone where he netted a header in the first half and the second was versus Bologna where he scored inside 90 seconds to lead Inter into a 2–1 home win, the first after eight league matches.
