Local derbies are something special, and it is important for punters to be aware of these matches, since they are often very tight matches, where criteria like form and league standings have no real influence. All that matters is NOT to lose the derby. Local derbies tend to end with a draw, because the fear of losing the game is much higher than the will to win.
Rome vs Lazio:
These teams make use of the same arena (Olympic Stadium in Rome), a very important game for both parts. This is Italy's most probable draw !
Torino - Juventus
Share the same home arena. This game does not end with a draw very often, but Torino wins almost as many games as Juve.
Inter Milan - AC Milan
Share the same arena. Rather difficult to predict, as these teams don't seem to go for the draw.
Genoa - Sampdoria
Share the same arena. Often ends with a draw. Genoa (when in the same division) provide hard opposition for Samp, and often stand a good chance against their more known opponents.
