Eder admits new Inter Milan boss Frank de Boer wants a different style of football.
The striker was speaking after their International Champions Cup win over Celtic.
“Aside from the goal, it was a good performance and an important one for me, as I hadn't played a match since July 2," Italy international Eder told Inter Channel.
“I saw the team in really good shape. The Coach asked us to immediately build from his style of football and identity, so remaining compact, tight and understanding the various moments of the game.
“We have to know when to press and when to play a little deeper. I am working well and need to improve a great deal in order to be more important for the squad."
