De Rossi is set to make his comeback from a three-match ban.
“De Rossi is not a problem or a bum note for me, but he hasn’t performed the way he should’ve,” Zeman told TG1.
“He has not integrated himself into the squad. He is an important player for me and I hope he can perform the way he did in past seasons.”
The Coach was asked whether there was truth in the reports of clashes behind the scenes between the two men.
“I never had problems with him. I was disappointed with his words after the defeat to Juventus, but that is in the past now.”
