Roma midfielder Alessandro Florenzi feels they will learn a lot about themselves against Juventus on Saturday night.
Roma have emerged this season as an outside bet for the Serie A title.
Florenzi said, “It will be a fundamental game for Roma's growth, it's worth three points like all the others but it's a match which will say how we're set and what point we're at.
“First place [in the Champions League] gives us an answer but we have to do it in the league too and not just against Juventus.
“Who would I take from Juventus? [Paulo] Dybala, he's a champion. They're a great team and it's never easy to play in Turin, we need to reverse the negative trend in their home and score points.
“It won't be a game to decide who wins the Scudetto."
