Eder says there's self-belief now surging through Inter Milan.
Inter enjoyed a morale-boosting victory over Juventus on Sunday.
"We are happy because we put in a top level performance," Eder told Inter Channel after Sunday's 2-1 Derby d'Italia win.
“We are slowly managing to put what the Coach wants on to the pitch and that pleases us. Now we know we need to improve, even if the Juve game represents something that will give us confidence for the future.
“I am pleased to work hard for the team, because that's how I see the world. If my sacrifice helps Mauro Icardi score and the team to win, then I am just as happy as if I'd scored."
