AC Milan midfielder Nigel de Jong says they'll know more about themselves after their clash with Juventus.
Milan boast a 100 per cent record so far this season.
De Jong said: "Juve have won the League title in each of the last three years - we do not have to discover them. In the Champions League they won and with conviction.
"To have the chance of success we must begin fighting from the first minute.
"Will it be the first real test for the new Milan? Certainly, but it will also be for them.
"Who would I take out of the Juve team if I could? It would be Tevez. I have known Carlitos well in Manchester and he is a true warrior, he is a crucial piece of the current Juventus.
"How will Max Allegri be received by supporters? I do not know and do not care much - this is a topic just for you journalists.
"What matters is the end result and the three points to win against Juve, if we are to succeed."
