Losing full points in one games make the first position standing gone and replace by second position team, looking forward if bigger team like Inter, Juventus and Milan back consistent performance I think they have chance lead Serie A standing position awhile. I doubt with AS Roma how many weeks keep consistent performance depending again with bigger team always failed get full points.
The standings in Serie A can still change with just one game. So although now things are not very good for some clubs but the opportunity to return to the top position in the table is very wide open. Moreover, they still haven't all met in this first leg. There will still be matches where they have to beat each other in order to crawl up to the top of the standings. This Serie A season is different from the previous season, where many clubs joined the competition for the best position.
the expectations of many people, at the beginning of this season the two big teams were very inconsistent. Especially Juventus in 7 matches only
won two match in Serie A, this is a very bad record, it looks like Juventus must immediately change their coach if they performance want to improve.
Don't be in a hurry to say they have to change coaches, because there's no guarantee for them that changing coaches will improve their performance. They must first evaluate from the whole, what was wrong with them that caused them to play badly as they are now. Monotonous strategy factor? Players who do not understand the strategy so that it is difficult for them to implement it? Or there are other problems that come from outside. I understand very well, the coach will be the first to blame when he finds a bad result. However, it must be evaluated before making a decision.
