Napoli and AC Milan's opponents are relatively easy. Udinese and Cagliari are relatively weak teams. They have no ability to win against Napoli and AC Milan. We will probably see the dominations of Napoli and AC Milan in these two matches.
Their opponents are very difficult for Inter Milan. Fiorentina is not a weak team. Moreover, Inter Milan is not in their best form now. They were able to win only one of the last 5 matches. So a win against Fiorentina in today's match will be difficult for Inter Milan.
I don't think there should be any surprises today with Milan and Napoli, but there's a question mark on Inter! This is a race for the first place, the favorites have to get those three points against weaker opponents, if not now and then when?
I agree that today Inter has the toughest opponent, Fiorentina is not a team to be underestimated, and Inter is not in top form lately, this will be an interesting match where draw looks very possible, maybe Inter draw no bet can be a good pick! Or maybe it would be good to miss that game and bet just on Milan and Napoli!? I have a bit more time to think about what bets to place!
