Juventus assistant coach Angelo Alessio says Inter Milan are a genuine threat to their title.
Inter stunned Juve in Turin on Saturday.
Alessio said: "After the first 20 minutes we could have been 3-0 up, but we made a lot of mistakes and that cost us dearly.
"Inter are a good team and I think they can compete for the title. You only have to look at their attack to see they're a great team."
