The 19-year-old sustained a thigh injury during training on Monday and could miss the Europa League tie.
He said: “I did tests at the clinic and there is a little problem. It is only an overload of the muscle, and I hope to start against Rosenborg.
“When I was playing with the ball, I fell to the ground, and when I got up I felt pain. But I’m training with the physios, so we will see.”
