The two merda teams in Milano, more entertainment. Im pretty sure they gonna be fights WHEN Milan gonna get their penalty in the game.
In last season derbies we saw 2 penalties for Milan, 2 red cards for Milan (Abate, Cassano) and 1 red card for Inter (Chivu). Milan won both matches, 1:0 and 3:0 respectively.
In the 2009/2010 season we saw 1 penalty for Inter, 1 penalty for Milan (missed by Ronaldinho), 1 red card for Milan (Gattuso) and 2 red cards for Inter (Lucio and Sneijder for clapping at a ref's decision). Inter won both matches, 4:0 and 2:0.
Overall, in the last 4 serie A matches between Inter and Milan there were 4 penalties (3 Milan, 1 Inter) and 6 red cards (3 Milan, 3 Inter). On 3 of the 4 matches there was at least 1 penalty and on all 4 there was at least 1 red card.
No reason not to expect anything similar tomorrow.
