Sampdoria coach Vincenzo Montella says they'll miss Eder.
Eder was sold to Inter Milan last week.
Montella said: "I am the Coach of Sampdoria, not the owner of the club. I can give a professional evaluation of the players, but that's it.
“Eder was an important player, so obviously with him gone, we are missing something. At this moment we are not a complete squad that can face the rest of the season and the club knows this."
