Juventus left-back Alex Sandro regards Atalanta as a title rival.
Atalanta closed on leaders Juve to three points after they thrashed Udinese 7-1 on Sunday.
"This year there are many strong teams: I believe that Inter, Napoli and Atalanta will challenge us right to the end," Alex Sandro told Sky Sport Italia.
He also had a word for Juve teammate Matthijs de Ligt.
"We need to give him time. I don't see him in difficulty. On the contrary, he seems to me to be growing. He is a very strong defender."
