what do you say!

this defeat was expected because this 23 match unbeaten run had to end

The ref surely was not up to it, but if Juve lost, it was only because of Inzaghi.
And don't be so happy, because not only stupid persons like me think that if Lazio will beat Juve next week, they are at -3 and everything will be open again.
Remeber: Juve started playing in summer, 2 months before the other teams. They'll get tired.

p.s. why does the "best" player in the world not score?

A lost is a lost,just get over it,anyways Juve has an important match ahead of them.Accept the loss ,there we can do about it.
