There's no crisis, just the usual black December period for us. Last year we had the same problem in the same period and we were 6 points behind Milan. Now we're actually in a better position since we're just "4 points" adrift.
Milan and Roma will go through bad periods as well, especially since both teams since to rely on 11 fixed players unlike Juve who can rely on different players at different times.
Imagine if Shevcenko goes out of form (like it usually happens to him around the December/January period onwards) just like DP. Would Milan still win easily? No I doubt it cos they rely heavily on him, and only a Kaka magic saved them on Saturday when the Ukranian could not put the goal past Bucci.
