Inter Milan boss Roberto Mancini is tightlipped on an Eder debut against AC Milan.
Eder signed from Sampdoria on Friday.
“This is a great chance for him and for us. Eder can give us a big hand, but we mustn't think that with him in the squad everything will suddenly change," warned Mancini.
“When I said I could've scored some of the chances aged 50, it was just a joke, but people took it as something offensive.
"I said nothing wrong. We have an excellent rapport with the players and we say everything face to face."
