Roma midfielder Diego Perotti is impressed by new teammate Cengiz Under.

Under has joined Roma from Basaksehir this summer.

“He's very strong," Perotti told Roma TV.

“He has a good left foot, he's quick, maybe he's a bit small and he doesn't have much experience in contact.

“He has to gain some muscle, but you can see right away when someone is good. We understand that he'll be an important player for us."
