Roma coach Jose Mourinho says Gini Wijnaldum will be gradually introduced.
The PSG loanee is fully fit after recovering from a leg fracture in August.
Mourinho, ahead of their Europa League clash with Salzburg, said: "He won't be a starter tomorrow.
"Let's see game after game. He's training continuously and his work data is positive.
"But training is one thing and match pace is another thing."
