Icardi struck twice in victory over Pescara.
De Boer stated: “I don't see why Icardi and Gabigol can't play together. Good players always adapt and Gabigol can play in three different positions. We've got a long period ahead of us and will need everyone.
“Gabigol proved himself to be a fantastic player, all the European clubs want him. I hope he will soon be a part of this fantastic team."
