That's why I said that the warm-up matches are not very important, Serie A drew AC Milan in the first match where the opposition was not too difficult for them. A team that beat a team like Manchester City in a warm-up match could not beat an easy team in the main stage. Earning a point at the start means falling two points behind all other teams. AC Milan must be very serious in the next matches as they have just played one match in the Italian league and still have all their matches to go. The day on which the second match is played should be considered as the final match for them and they should win that match by any means. If they can play every match with such importance, it will be easy for them to win against their opponents.
Every team actually has to feel more strongly that every match, whether at the start or not, has to be the most important match. Because losing points at the start will only mean they have to catch up in the next match. But results that are difficult to predict at the start of the season are quite common in every season. And a draw is also not a bad result compared to a team dropping points. AC Milan and Inter Milan both only got 1 point and that is still quite good compared to Napoli who still haven't got a single point. In fact, they actually suffered a crushing defeat by Verona.
In the second week, all teams will definitely play more seriously and I think the top team will ultimately be the team that wins and gets full points. Because it would be very difficult to believe if AC Milan and other favorite teams could only get 1 point back in the second week.
