Here are the Serie A games played so far by the so-called big three and the next two games.
and next two:
Samp - Inter
Lazio - Inter
and the next two
and the next two:
Only a blind man can not notice that Inter out of the three has the most difficult schedule in the first 11 games by a proverbial country mile. Inter had or has to play no fewer then 6 derbies in those out of which 5 are away from home. Meanwhile, Juve has only 4, 2 of which are at home and one of the away derbies was against Udinese which, as far as I am concerned since the Iaquinta case are officially Juventus B. Milan got it even easier: he has 4 derbies, 3 of which are at home and the one away they have lost already.
So before anyone starts quitting, whining about having fallen behind or admiring some so-called records, look at who is it that played against whom and where. I think it does have a tad bit to do with the results so far.
